[Closed] ERR_CERT_COMMON_NAME_INVALID error leading to no menu styling following migratio

Hi,

Thank you for contacting the support.

I checked your website and the certificate seems to be valid. However, can you please explain more about it that where and when you receive this error? I checked in browser console and network tab and couldn't find anything like this.

For the WPML Language Switcher, I don't se one in the menu, but at bottom (in the footer) and it seems to work fine.

On the other hand I'll advise to fix the followings in your site (as per the debug information):

IMPORTANT: Take full backup of your website and database beforehand.

1) Fix "WP Memory Limit" to at least 128MB while 256MB is recommended. You can fix this in your wp-config.php file by adding following code:

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

Remember to add these lines before the line where it says:
/* That's all, stop editing! Happy publishing. */

2) Update WPML plugins to the latest ones, as well as, other plugins and theme (if needed).

3) Try disabling any firewalls, caching and/or redirections (plugins or server based) and recheck.

Please let me know and I'll try my best to help you further on the matter.

Regards.
