[Assigned] PHP Fatal error in PreloadThemeMoFile.php

Thank you for contacting WPML support. While you are waiting for one of my colleagues to take this ticket and work on it, let me provide you with the first debugging steps and try to help with the issue quickly.

1) This error is usually caused by the limitation of PHP setting max_execution_time on your site. You can follow the article below to increase this setting value or contact your hosting support to ask for help with this issue and check the site again.

2) Disable any additional plugins unrelated to WPML and its add-ons.

3) If the problem goes away, start reactivating the plugins one by one or activate them in small groups. Do this to check where the problem is reoccurring and see which plugin is causing the problem.

4) If this didn't resolve the cause of the issue, please switch to a default theme like Twenty Twenty-One to see if the issue might be related to the theme.

Furthermore, strings in your database will not be removed unless you delete them manually.

Please let me know how it goes.

Hello,

In this particular file and on the mentioned line WPML String Translation is trying to execute the function load_textdomain().

load_textdomain( $fileResult->domain, $fileResult->file_path );

The load_textdomain() function is used to load the language files for a particular domain. The parameters passed are:

$fileResult->domain: This is the text domain for which the .mo file will be loaded.
$fileResult->file_path: This is the path to the .mo file.

Can you please revise if your site has the folder /wp-content/languages and its subfolder wp-content/languages/wpml?

Further the issue could be related to the following folders, but I doubt that at this point:

wp-content/themes/[your-theme]/languages/
wp-content/plugins/[your-plugin]/languages/

Best regards
Andreas

Could you please enable WB DEBUG and let me know if you find any errors related to load_textdomain() or other errors?

Hi,

I would like to offer to take a closer look and request temporary access (wp-admin and FTP) to the site to investigate the issue further.

The required fields are below the comment section when you log in to leave the next reply. The information you provide is private, meaning only you and I can see and access it.

IMPORTANT
Please be sure to back up the site and database before granting us access.

If you can't see the "wp-admin / FTP" fields, your post and site login details will be set to "PUBLIC". DO NOT publish the data unless you see the required wp-admin / FTP fields.

I may need to install a plugin called "All In One WP Migration" here to create a copy of the site that I can use to investigate the issue further.

However, I would also be very grateful if you could provide a staging site or copy of the website from your server for this purpose.

If you have any questions about creating such a staging site, you can consult your hosting provider. Please note that WPML must also be registered on this staging site at https://wpml.org/de/account/websites/.

If you are not able to provide such a copy of the website for testing, please let me know on this ticket.

The private reply form looks like this:

Does this mean that if you disable any plugin and run the site only with WPML, the load time on backend is 12 seconds or higher?

Could you please try our release candidate version for WPML 4.7?

Go to: https://wpml.org/account/downloads/

On the dropdown on the top right switch to "Beta".

Download:

WPML Multilingual CMS 4.7.0.rc.1
WPML String Translation 3.3.0.rc.1

If needed, also install the addons for WCML, ACFML, and WPML SEO found on the same page.

If these updates will not solve the issue, please let me know.

Yes, if you are using "Advance Custom Fields Multilingual" then please give this workaround a try:

If this will not solve the issue, it would be great if you could provide me access to a test environment or provide me access to the live site so that I can take a copy using the plugin "All In One WP Migration".

The private reply form is enabled again.
