For unknown reason, I got a 500 Internal Server Error when trying to access wp-admin. I can still access the site fine but I can't do anything if I can't access those menus that got affected by 500 Internal Server Error.
I have tried recreate a new .htaccess file, create php.ini, disabling all plugins, and re-upload wp-admin and wp-includes but no luck.
What else needs to be done in order to make the site editable again?
thank you
