After installing ISPConfig 18.104.22.168 the past week, I got stuck in the suPHP config. "Premature end of scripts", "Handler "x-http-suphp" not found" and additionally "Handler not found in configuration" Tried several settings, search many webpages. At last I change /etc/suphp.conf [handlers] x-http-suphp = "php:/usr/bin/php-cgi5" (added the bold stuff) and that did the trick. My question is: Is this finally the right setting, or should i change some setting in another place? I hope this helps others too!
