I don't know why but since 2 days my server don't work as it should. If I activate PHP as CGI or FCGId then PHP are not parsed and is served as download file with source code. I have to force every Virtual Server to use mod_php. To do so, I commented out every lines with php_admin_value engine Off to re-enable every Virtual Server quickly. But now I have rights problems with apache/php.
I find some thread where they say to deactivcate module php_cgi in Servers -> Apache Webserver -> Click on "Global Configuration" tab -> choose "Configure Apache Modules". But I don't have Configure Apache Modules in Global Configuration tab :-(
Here is my configuration :
Thank you for your help.
