Hello, my site was working perfectly and is in production.

Now since today, for an unknown reason visitors keep having
in the translated language (french), in what looks like random pages, sometimes blog, sometimes courses, but always in translated language.

What is causing that ? and can I do to solve this ? can you investigate why this is happening ?? thanks

Please I saw in the forum you keep telling to deactivate all plug ins and change the theme to twenty-I-dont-know-what, but don't ask me that, the site is currently in production and I can't do that. This is clearly an issue with your translation system, the site works good in english..

Thanks in advance for your help.

Hi There,

I ran a test visiting between all your pages in French for a substantial period of time and I was not able to reproduce any errors.

An error 500 usually will stem from a memory-related issue but some other times a fatal error in the execution of code can also trigger it.

It would be good to take a look at your error log to see if any Fatal Errors were triggered.
You can see how to enable debug logging here:

Go in your wp-config.php file and look for define(‘WP_DEBUG’, false);. Change it to:
define('WP_DEBUG', true);

Edit your wp-config.php file and add these lines, just before it says 'stop editing here':

ini_set('error_reporting', E_ALL);
ini_set('error_log', dirname(__FILE__) . '');

This will create an error_log.txt file in your site's root directory. Please send me its contents.

In the meantime also update your MySQL version to 5.6 or higher.

My issue is resolved now I reinstall a backup and the problem is gone, but I'm afraid it will come back 🙁
