[Resolved] Critical Error Occurs Upon Activating WPML Plugin

Hi,

Thank you for contacting WPML Support. Could you please follow the below steps and let me know how it goes:

1. The current WP Memory Limit on your site is 40MB. The WP memory limit needs to be increased, it's different from PHP memory. PHP memory is fine but WordPress uses 40MB as default in your site. The minimum requirements for WPML are 128MB: https://wpml.org/home/minimum-requirements/

Please add this line to your wp-config.php file to increase WP memory, wp-config.php file is located in the root of your WP install:

/* WP Memory Limit */
define('WP_MEMORY_LIMIT', '256M');

You can add it anywhere in your file. I recommend placing it right before the following line:

/* That's all, stop editing! Happy blogging. */

2. If the issue persists after increasing WP memory, please enable error reporting on your site as we need to see the details of the latest error log to understand the cause of the issue better. To enable it, open your ‘wp-config.php’ file and look for ‘define(‘WP_DEBUG’, false);’. Change it to:

// Enable WP_DEBUG mode
define( 'WP_DEBUG', true );
 
// Enable Debug logging to the /wp-content/debug.log file
define( 'WP_DEBUG_LOG', true );
 
// Disable display of errors and warnings
define( 'WP_DEBUG_DISPLAY', false );
@ini_set( 'display_errors', 0 );
 
define( 'SCRIPT_DEBUG', true );

After adding the above code, please try activating the WPML plugin again, and if this process creates a debug.log file in your site's wp-content directory. Please send us its contents.

Here is a doc for more details:

3. Are you trying to configure WPML for the first time on this site or do you already have translated data by WPML?

Kindly let me know the results,
Thank you

Thanks for the additional details. To take a closer look at this issue, please provide temporary access (WP-Admin and FTP Login info) to your site (preferably staging site), so that I can look into your setup and debug the issue.

Your next answer will be private, meaning only you and I can access it.

=== Please backup your database and website ===

✙ I would additionally need your permission to deactivate and reactivate Plugins and the Theme and to change configurations on the site. This is also a reason the backup is essential.

Thank you
