For some unknown reason, my site has suddenly started putting an error line:
500 Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
I checked the server error log :
- mod_fcgid: stderr: PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, first array member is not a valid class name or object in /var/www/vhosts/polishdinner.de/httpdocs/wp-includes/plugin.php on line 406
- Options FollowSymLinks or SymLinksIfOwnerMatch is off which implies that RewriteRule directive is forbidden: /var/www/vhosts/polishdinner.de/httpdocs/index.pl
Help! What I have to do ? I'm just a cook.
Any help much appreciated
