I made suphp installation as described http://www.howtoforge.com/suphp_fedora7_centos5_with_ispconfig but after apache restart I am not able to open php files anymore. Server said that is unknown file type application/x-httpd-php. Seems that server php is not working anymore because everything is working normally with html files. I checked vhosts and find that suphp lines are added to server conf file. suexec is disabled on ispconfig panel. I checked server logs and find one line which look strange: [notice] suEXEC mechanism enabled... I forgot something or what is my problem solution?
