Hi Pierre,

with active APCu Manager I cannot use wp commands, I always get:

>Parse error: syntax error, unexpected ‘|’, expecting variable (T_VARIABLE) in ../wp-content/plugins/apcu-manager/includes/libraries/decalog-sdk/EventsLogger.php on line 76

With deactivated APCu, but still activated Decalog plugin, the error changes to:

>Parse error: syntax error, unexpected ‘|’, expecting variable (T_VARIABLE) in ../wp-content/plugins/decalog/includes/api/class-logger.php on line 60

Everything is up to date, PHP is 8.1 – any idea what to do about this?

Regards, André

Hello Pierre,

we discovered an issue with wpml. I have multiple languages and we use Elementor (if that helps). As soon as we activate APCu Manager, we have conflict between homepages.

# how to reproduce
Let’s say I have the original page, everything is good. If I create another language’s version of the page, links are the good ones (meaning different links per languages on each items in carousels) and our translations work too.
As soon as I activate APCu Manager, links don’t work anymore. It kind of “copies” the links from a language to another and all 3 homepages have now the same links (randomly between the 3 languages). They don’t differ from a language to another.

Should I configure something ?
Thank you

Hello,

I have this error that just appeared and causes the site to brake.

[02-Oct-2024 10:33:40 UTC] PHP Fatal error: Cannot declare class WP_Object_Cache, because the name is already in use in .../wp-content/plugins/apcu-manager/includes/api/object-class.php on line 18

The issue appeared after I fixed something in an override where we kept on using $product->id instead of $product->get_id(); That’s not really related I guess but I think it blocked the error before and right after I fixed it, the WP_Object_Cache appeared.

I deactivated the apcu manager plugin in the meantime. Any idea what causes this ? I thought it could be because of another cache plugin but I have only one (Cloudfare) and tried to deactivate it but it doesn’t change anything.
Thank you

What is the jsDelivr checkbox for and is it better to check it

Hello everyone,

since I started using the plugin the web space has been flooded with folders and files, e.g. arise every time a new post is saved. Is there a setting option to prevent this?

Folders named like: 0315ebddd850a1127c616ee69….. > dist

Thank you very much for an answer.

Dear Pierre,

I was wondering if you would consider adding WP-CLI commands to the plugin that would allow users to easily enable or disable Delivrjs CDN services. This feature would provide added flexibility for users who manage their WordPress installations via the command line, especially when CDN management is involved in specific workflows.

This addition would be a great enhancement for users who rely on WP-CLI for automation, and I believe it aligns well with the plugin’s current focus on performance and control.

Thank you for considering this request, and I look forward to any future developments with the plugin.

Best regards.

APCu 4.0.0
WP CLI 2.11.0

Hi Pierre,

I discovered that APCu is blocking the WP CLI functionality. While using “wp plugin deactivate plugin-name” command, command line says Plugin ‘plugin-name’ deactivated. But indeed if you check it from wp-admin/plugins.php all recently plugins’s status are still active and wouldn’t change. I am bulk deactivating and activating plugins via WP CLI. I tested the process thorougly and finally when I deactivated APCu from WP Dashboard, WP CLI plugin commands started to work fine again.

I hope you can replicate the issue and find the culprit easily.

Best regards

Hi,

i see the plugin ist tested under WP 6.5.5 … Work it under WP 6.6.1 ?

Greetings

I use woocommerce which is synchronized with the “Pintpoint booking System pro” booking module. This allows you to create live bookings. As the user fills out the form, the plugin checks the availability of services in real time and provides instant feedback. Could the plugin be compatible? Thanks in advance

Thank you for the excellent plugin.
I would like to have support up to php7.4 as some systems are in the process of being migrated.
Please help us.

I’ve been having endless problems with WooCommerce upgrades for the last few years, where WC constantly wants to update the database and yet no matter how many times I go through the update process it always wants to update it again immediately after the upgrade has completed. Only today did it occur to me to try disabling APCu Manager to see if there was a link, and indeed there was: as soon as APCu Manager was disabled I got the “thanks for updating” message and the WooCommerce database version matched the WooCommerce version as expected.

I’m not sure whether this counts as an APCu Manager problem or a WooCommerce problem. Clearly the object cache needs to be cleared as part of the WC DB upgrade process. But is that something WooCommerce need to implement on their side, or is it something that APCu Manager needs to detect and automatically flush on its side?

Hi there!

1st, thanks for this great plugin. It works faster than Redis Object Cache Pro plugin.

I have a wish though.

I don’t want to ObjectCache the frontend of the website but only the backend admin area to speed things up, as i am using litespeedcache plugin for Page-caching for the frontend. I tried disabling the APCu-Manager plugin from working in the frontend of the site, but that doesn’t stops the plugin from Object caching for the frontend – of course that wouldn’t I guess, but I tried it anyways.

I just wish there was an “option” in the plugin to only cache the backend admin area of the WordPress site —- it would have been great and also the cache-limit wouldn’t have been reached and everything on the server would have remained minimal and at the same time the WordPress Admin area would have remained extremely fast.

Thanks in advance. God bless.

Currently, the object-cache.php doesn’t appear to work with the WP abstraction layer.

None of the commands in WP CLI, for example, seems to be functioning. wp cache type returns ‘Unknown’ instead of ‘APC’ because the following class isn’t used:

	// Test for APC object cache (https://www.ads-software.com/extend/plugins/apc/)
		} elseif ( class_exists( 'APC_Object_Cache' ) ) {
			$message = 'APC';

wp_cache_supports() is missing and so all features test false. wp cache flush also doesn’t flush any APCu cache.

Implementing the functions underlying WP CLI commands can be important because some plugins rely on these functions to purge object cache, and such code as wp_cache_flush() will fail if a user happens to be using APCu.

Would it be possible for this aspect of the plugin to be improved?

Hello Pierre
I have a problem with version 3.9.0, WooCommerce and WooCommerce PayPal Payments are installed. For the moment I prefer to stay on 3.8.0. while waiting for corrections to come.

Thank you for this excellent plugin

Hello,

I have been checking the forum related to errors since version 3.8.x in all of them I presented the error. I have the CloudFlare and WooCommerce PayPal Payments plugins. If you could fix the error it would be great. For now go back to version 3.8.0.

Thank you

A few days ago, a version 3.8.1 of APCu Manager was pushed by mistake on the WordPress directory. It’s a mistake for which I’m totally responsible and which results from a poorly mastered CI/CD chain (it is now fixed). For your information, this error impacted almost all my plugins.
As soon as I discovered the problem, I immediately released a first corrective version (3.8.2). Then a definitive fix for the root cause (3.8.3).

The current 3.8.3 version is working smoothly for 99% of users.

Unfortunately, this release also highlighted incompatibility with some third-party plugins that had not been updated for a long time and/or embedding obsolete libraries. This is the case, for example, with the Cloudflare plugin.

So, if you’re in this situation, here’s what I recommend:

1 – fully remove APCu Manager (via ftp, ssh, etc.) and don’t forget to remove the wp-content\object-cache.php

2 – reinstall and activate APCu Manager

If activation fail, try to identify the plugin which is not compatible and tell me here what’s its name. I will try my best to contact authors and see what’s achievable on a case-by-case basis.

Fatal error: Declaration of DecaLog\EventsLogger::emergency(Stringable|string $message, array $context = []): void must be compatible with Psr\Log\LoggerInterface::emergency($message, array $context = []) in?/home/edcpzvnb/public_html/wp-content/plugins/apcu-manager/includes/libraries/decalog-sdk/EventsLogger.php?on line?325

The latest update crashes access to my dashboard and I get the following php error:

Je ne peux rien activité dans l’extension, j’ai WordPress 6.4.3 et php 8.1.23 (Supporte les valeurs 64 bits) sur un serveur d’OVH.

Dear Pierre,

Thanks for this plugin. It does seem to help our pages a lot.
There is only one bit of trouble we’ve been having, though. When APCu is active, users keep constantly getting automatically logged out. And have to re-log in again.

Do you have any ideas as to why?

We’re Running
WP (latest)
PHP 8.1.27
DIVI (latest)
WPML (latest)

Thanks for any help.

Best Regards,
Allan

Bonjour,

Depuis que j’ai installé APCu Manager, j’ai régulièrement des messages dans Santé du site du style “L’évènement planifié apcm_apcu_stats, est en retard. Votre site fonctionne toujours, mais cela peut indiquer que la planification des articles ou des mises à jour automatisées peuvent ne pas fonctionner comme prévu.”. Il peut s’agir également de wp_cache_gc, wp_privacy_delete_old_export_file, feedzy_cron, wp_version_check, wp_udate_plugin … Lorsque cela arrive, le CRON ne fonctionne plus. Je dois à chaque fois désactiver le cache objet puis le réactiver.

Capture d’écran des statistiques.

J’ai désactivé le cache objet durant 24h et je n’ai plus eu de soucis.

Version APCu (mmap) 5.1.23, PHP 8.1

Merci

Hi!

I have repeated errors in the debug.log. Here are the errors :

[06-Nov-2023 09:52:22 UTC] Erreur d’événement de replanification de tache pour le crochet apcm_apcu_stats. Code d’erreur?:?invalid_schedule. Message d’erreur?:?L’évènement planifié n’existe pas.. Données?:?{“schedule”:”five_minutes”,”args”:[],”interval”:300}

I’m under WordPress 6.3.2, Php 8.2
I have the following plugin : APCu Manager, Contact Form 7, Cookie Notice & Compliance for GDPR / CCPA, NinjaFirewall (WP+), Redux Framework, SEOPress, SEOPress PRO, WordPress Backup & Security Plugin – BlogVault, WP Rocket, WP-PageNavi, WP-PostRatings, WP-PostViews

All the plugins are up to date in their respective version. These errors occurs all day every 10 seconds or so.

Can you please help me?

Does your excellent plugin work well with PHP 8.2.9?
And with a litespeed server a litespeed cache plugin for wordpress?

I can’t make any WordPress settings changes with APCu on. Changing settings in plugins, even activating plugins doesn’t work. When I deactivate the plugin, things work again. What can be done about this?

Just installed the plugin but it’s not caching the page (see link below) despite reloading the page several times. I have checked and saved the Apcu box in my cPanel so nothing is wrong on my side. The statistics page says “0 objects”. Please assist. Thanks!

• This topic was modified 1 year, 2 months ago by richard1250.

After installing and activating APCu Manager there is a banner saying “APCu Manager has been correctly installed.”.

So, I go to the settings page to activate the object cache, but all the checkboxes are disabled and cannot be clicked. What could be the reason for that? Perhaps a conflict with another caching plugin? I have “Autoptimize” and “WP Super Cache” (by Automattic) installed.

Thank you in advance for your assistance!

Hi,

since I activated APCu Manager, I have some problems with broken sessions on my page. Sometimes I have to login again on every page in the dashboard. Everythings works again after waiting a few minutes or when disabling the plugin. Aside from that the plugin speed up the page very well.

Unfortunately it also causes some trouble with Woocommerce payments.

Any ideas how I could further investigate the issue?

Is there a way to blacklist/whitelist what can be cached?

I also have WP Rocket enabled and it is a Multisite setup.

Thank you.
