Hello,

After deactivating Woocommerce Multilingual, if you encounter the same performance issue, it will show that the problem might be in conjunction with another plugin on your website.

To detect that, you will need to do as follows:

- IMPORTANT STEP! Create a backup of your website. Or better approach will be to test this on a copy/staging version of the website to avoid any disruption of a live website.
- Switch to the default theme such as "TwentyTwenty" by going to "WordPress Dashboard > Appearance > themes".
- Go to "WordPress Dashboard > Plugins" and deactivate all plugins except:
. WPML Multilingual CMS
. WPML String translation
. WooCommerce
. WooCommerce Multilingual
- Check if you can still recreate the issue.
- If not, re-activate your plugins one by one and check the issue each time to find out the plugin that causes the problem.

Thanks.

Howdy!

WordPress has 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, WPML Multilingual CMS.

First, visit your website (hidden link) and check for any visible issues. Next, visit the page where the error was caught (hidden link) and check for any visible issues.

Please contact your host for assistance with investigating this issue further.

If your site appears broken and you can't access your dashboard normally, WordPress now has a special "recovery mode". This lets you safely login to your dashboard and investigate further.

hidden link

To keep your site safe, this link will expire in 1 day. Don't worry about that, though: a new link will be emailed to you if the error occurs again after it expires.

When seeking help with this issue, you may be asked for some of the following information:
WordPress version 6.9.4
Active theme: Bumbleb Child (version 1.0.0)
Current plugin: WPML Multilingual CMS (version 4.9.2.1)
PHP version 8.3.30

Hello,

Thank you for the information. I still did not get what the result of the steps I mentioned was to check the minimal setup with WooCommerce and WPML.

That is important to know to be able to go forward.

Regarding your guess for the WPML version, you can simply update to version 4.9.2.1 and see the result:

- Go to "WordPress Dashboard > Plugins > Add new > Commercial (tab)".
- Click the "Check for Updates" button.
- Update WPML and its addons there.

For more information:
https://wpml.org/faq/install-wpml/#automated-updates

You can always downgrade to 4.9.2:

- Go to https://wpml.org/account/downloads/
- Click Download WPML manually
- Click the i icon next to WPML Multilingual CMS (screenshot)
- In the version history, find 4.9.2 and download it.
- After that, you can install it on your WordPress Dashboard.

Thanks.
