[Resolved] Theme customizer critical error

Hi,

Thank you for contacting the support forum.
Before your ticket is assigned to one of my colleagues, please allow me to walk you through some initial debugging steps. This will help speed up the support process.

The error is because of an invalid translation either coming from MO file or added by the translator to WPML.
Please see this errata https://wpml.org/errata/php-8-php-fatal-error-uncaught-valueerror-unknown-format-specifier-in/

To fix this issue, you can go the to file and line number that is mentioned in the error message and copy the string. You can then search this string in String Translation and try to fix it as per the errata.

Please try it and let us know.

Thanks

Hi there,

Thank you for contacting WPML support, I'd be happy to help you with this issue.

I would like to request temporary access (wp-admin and FTP) to your site to take a better look at the issue. It would be better to a testing site where the issue is replicated. Your next reply is set to private to share the info.

❌ IMPORTANT: Please backup your database and website before proceeding ❌
You can use this plugin to create the backup: 
https://wordpress.org/plugins/duplicator/
✙ I would need your permission to de-activate and re-activate Plugins and the Theme and to change configurations on the site if needed. This is also a reason the backup is critical.

While checking the debug info, I see that the WordPress Memory Limit is below the requirements. The minimum requirements are 128M, but we do recommend 256M and the debug information of your site shows it set to 40M. Please check this link for more details
https://wpml.org/home/minimum-requirements/.
You can increase it by adding the following code in your wp-config.php file, right before the /* That’s all, stop editing! Happy publishing. */ line:


define( 'WP_MAX_MEMORY_LIMIT', '256M' );
define( 'WP_MEMORY_LIMIT', '128M' );

After adding the code you can confirm that the memory was changed correctly from WPML > Support > WordPress > Memory limit.

Look forward to your reply.
Thanks
