Hi there, thanks for offering a hand to support!

I figured it out. I use ATUM Inventory to manage stock levels. I set WooCommerce Low Stock threshold at 2, Out of Stock at 0.

In ATUM Inventory, for all Variable Products I set the parent stock to 1 (variations have their own stock levels of course).

This helped products not show “Out of Stock” on the store, but didn’t allow for quantity field/selector.

To fix this, I updated all Variable Products parent stock to 3 instead of 1. This is above WooCommerce Low Stock threshold of 2, so now quantity field selector works for each variation.

Thanks for the offers to help!

@quadlayers Just want to ensure you saw the above message for LINE 70.

Thanks!

@quadlayers

Thanks, I have updated to 1.9.3, and now the critical error has been replaced with this error:

Can you look into this please?

hello @quadlayers

I have updated to 1.8.8 and this has resolved the critical error on LINE 44 issue.

HOWEVER, now there is another critical error, LINE 35 in your plugin:

Can look into this please? I get daily emails with critical errors from QuadMenu, and have been getting them for almost 90 days straight. =(

OK thanks!

Awesome, I’ll have a look. Thanks Ben!

@quadlayers Can you look into this please?

Here is the Elementor code reference for is_preview_mode: https://code.elementor.com/methods/elementor-preview-is_preview_mode/

@quadlayers I have installed update 1.8.7 and think the error regarding LINE 40 is fixed, so thanks for that!

Now I receive a new error regarding LINE 44. Here is the email WordPress 5.2 sends me regarding new QuadMenu 1.8.7 issue:

[Subject] Your Site is Experiencing a Technical Issue

Howdy!

Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email.

In this case, WordPress caught an error with one of your plugins, QuadMenu.

First, visit your website (https://www.mydomain.com/) and check for any visible issues. Next, visit the page where the error was caught (https://www.mydomain.com/wp-login.php) and check for any visible issues.

Error Details
=============
An error of type E_ERROR was caused in line 44 of the file /home/cloudwaysapps.com/mydomain/public_html/wp-content/plugins/quadmenu/includes/3rd/elementor.php. Error message: Uncaught Error: Call to a member function is_preview_mode() on null in /home/cloudwaysapps.com/mydomain/public_html/wp-content/plugins/quadmenu/includes/3rd/elementor.php:44
Stack trace:

#6 /home/cloudwaysapps.com/mydomain/public_html/wp-includes/template.php(671): load_template('/home/2487

So this time it’s LINE 44 of quadmenu/includes/3rd/elementor.php. Apparently the call to a member function is_preview_mode() on null caused an error of type E_ERROR.

Can you look into it please?

Thanks for responding.

Would you mind reading through this thread? Your QuadMenu plugin has an error:

CRITICAL Uncaught Error: Call to a member function is_edit_mode() on null in /home/cloudwaysapps.com/mydomain/public_html/wp-content/plugins/quadmenu/includes/3rd/elementor.php:40

Can you review the doc I linked above? Perhaps there was an Elementor code change since your last update: https://code.elementor.com/methods/elementor-editor-is_edit_mode/

I get an email everyday since WordPress 5.2 that says QuadMenu has a critical error that must be fixed. There are no visible issues on my website, so don’t know how to diagnose other than you reviewing LINE 40 in the PHP file mentioned above.

FYI, SJ Elementor Addon also had this issue but the developer never resolved it:
https://www.ads-software.com/support/topic/fatal-error-call-to-a-member-function-is_edit_mode-on-null/

@quadlayers

Unfortunately I can’t describe the steps I took to reproduce the issue other than updating to WordPress 5.2.

Perhaps in tests you can try Astra theme, Elementor, and QuadMenu.

The QuadMenu plugin is working on my site, but have now received 24 daily emails sent by WordPress stating “Your Site is Experiencing a Technical Issue”.

In my first post, I outline where the critical error is:
/wp-content/plugins/quadmenu/includes/3rd/elementor.php - LINE 40

WordPress 5.2 does not like this line of code in your plugin:
if (!Elementor\Plugin::$instance->editor->is_edit_mode() && !Elementor\Plugin::$instance->preview->is_preview_mode()) {

I searched for some answers and will post what I found. I hope one of these leads towards a solution:
https://code.elementor.com/methods/elementor-editor-is_edit_mode/
https://github.com/WordPress/gutenberg/issues/15209
https://sourceforge.net/p/concretecms/discussion/814373/thread/b5bc70b9/

@quadlayers There’s been several versions of WP.org Elementor since I noticed this issue and each had the same problem. I’m currently on version 2.6.1.

Apologies @gioni as I’ve already expressed this in other support threads, but your solution is not fully correct. Even if you whitelist get_refreshed_fragments, other Woo elements still get blocked.

For WooCommerce users, here is a more complete Whitelist solution after testing in the wild:

?wc-ajax
edit-account

Hope that helps!

I discovered that WP Cerber was blocking edit-account function in antispam, as it thought these were bot actions.

I updated my current Antispam Query Whitelist to this:

?wc-ajax
edit-account

Upon testing, I can now successfully update password as customer role without getting blocked as attack vector.

For now the issue is resolved, but please add the above whitelist fix in documentation for all WooCommerce users. Without such WooCommerce will not function as intended.
