Critical error upon creating products

Hi @mumbomedianl

Thank you for reaching out!

The error logs you shared were probably generated when you have both WPML and WPRocket plugin active on your website, since the logs were from 4th August.

I found another thread related to this error as well: https://www.ads-software.com/support/topic/php-warning-illegal-offset-type-in-isset-or-empty-2/

So it looks like the issue was happening due to WPML and/or the WPRocket plugin.

You can try creating new product now and check if similar errors are generated today as well.

Also, in order for us to get a better understanding of your site setup, could you please share a copy of your website’s System Status Report?

You can get it by navigating to the WooCommerce / Status section of your site. Once there, click on the Get system report button and then copy it by clicking on the Copy for support button. Then paste it here in a comment.

Hi,
I’ve got the updated error logs here.

And here’s the reaction from WPML

This fatal error is coming from the plugin
facebook-for-woocommerce instead of WPML, it looks like they have some code to support WPML, but something might not be working as expected.

Hey @mumbomedianl,

Thanks for sending these logs and the System Status Report! It looks like you have a lot of plugins which are operating in a similar territory as the Facebook for WooCommerce extension.

If you can run it successfully while disabling WP-Rocket, I suggest first excluding the following pages from caching:

* Cart
* My Account
* Checkout

These pages need to stay dynamic since they display information specific to the current customer and their cart. More information on [configuring caching plugins for WooCommerce](https://docs.woocommerce.com/document/configuring-caching-plugins/).

You will find more information about [configuring WP-Rocket here](https://woocommerce.com/document/configuring-caching-plugins/#wprocket).

Please let us know if this helps solve the issue.

‘WP Rocket automatically excludes the “Cart”, “Checkout”, and “My Account” pages from the cache for the plugins listed above.’

At this moment the only thing in WPRocket i have turned on is the CDN.
Besides that, no form of caching is happening.

As soon as i turn off either WProcket, WPML or the Facebook plugin, i can add products without any issues.

I tried some other stuff.
Using the Twenty Twenty One theme doesn’t help.

I’ve turned off all plugins except for the neccesary ones and that gives the following error.

WProcket on, but in safemode.

Hey @mumbomedianl,

Do you mind taking a full backup and subsequently updating all your software? From a quick view of your system status I noticed that you have outdated versions of WPML Multilingual CMS and WP Rocket. You may have other plugins not running their latest versions.

• WPML released version 4.5.9 with bug fixes → read more here
• WP Rocket version 3.12.0.5 available → https://wp-rocket.me/changelog/

Most issues can be fixed after updating themes and plugins so you may want to follow this advice.

Let us know how it goes.

Hi Mirko,
WpRocket is up2date. This site is always been updated.
Beta’s we usually dont install, but in this case i’ve updated WPML to 4.5.9

No change. Problem still exists.

Hi @mumbomedianl,

WpRocket is up2date

Thanks for letting me know. Suggested to update as I saw this on your system status:

WP Rocket: door WP Media – 3.12.0.3

As a next step, do you mind following the conflict test guide to make sure the issue is not caused by a plugin/theme conflict with WooCommerce?

You can find a more detailed explanation on how to do a conflict test here: https://docs.woocommerce.com/document/how-to-test-for-conflicts/.

Let us know how that goes.

Right! Update. Found the issue (finally thanks to WPML)
Heartbeat was turned off. By tturning that back on, everything works again.

Hi @mumbomedianl

Good to know that the cause could be identified, and the issue is now resolved.
