I get the 500-error when i'm trying to enter the admin area (but the site works perfectly , just can't login to admin area) .
I tried removing all plugins (resetting plugins) , changing the current theme , & I even tried installing a new copy of wordpress in a new directory (of course i also tried clearing the HTACCESS file).
but the problem remains .
again both wordpress installations (my real site and the new testing one ) work fine , I can navigate through pages ,but when i try to login to /wp-admin ,it shows Internet Server Error. ( i checked error logs but couldn't find any helpful information)
Any help would be appreciated.
