[تم الحل] Saving failed only happens when WPML active.

so I observed a problem that some pages do not save until I deactivate your plugin. Hence I reached to your support few days before. I gave temporary access to my website to one of your colleagues and he tried to enable error reporting. But for some reason he said that the wp-config.php file is not visible and he has asked me to contact my hosting provider ( as sometimes the hosting provider may disable error reporting for security reasons )

I just opened FileZilla and I see the wp-config.php file, can you guide me what to do so I can enable error reporting?
