After installation of boxbilling and successfully getting it connected to the server by making the 1st order server went into Error 502 bad gate way . I noticed that my php5-fpm is also not running and I am not able to even reset it getting the following error : [FAIL] Restarting PHP5 FastCGI Process Manager: php5-fpm failed! Anyone can help me get my server back up ?
Please check the php.ini contents that's used for the php fpm. If it contains errors or outdated options php may fail to start.
