Hi,
Today I had the same problem twice. The problem is "Internal Server Error", means when someone wants to go to my web page receive this error (see pic.) :

On the server I have two websites and on the both sites is the same error when someone wants to enter on the web page.
Via Putty (Shell) I write this command:
"/script/restart-web" and "sh /script/fixweb" and "sh /script/fixphpfpm" but the problem is not solved.
After that I write this via Putty: "sh/script/restart-all" and I got this (see pic.)

Does someone can help me? I have installed the latest version Kloxo-mr and I have dedicated server. On the server I have just installed Kloxo-MR and nothing more. This to me today happened twice at intervals of 3-4 hours and I solved the problem in a way that I've reboot the Server over Putty (reboot).
Is the problem to apache or php-fpm ? I use php type "php_fpm_event" and php_Branch "php53u_(as_5.3.28)".
Regards
