On the moment, i've a Debian Etch server with php5-cgi and suPHP enabled. php5 and suPHP has been setup according: http://www.howtoforge.com/suphp_debian_etch_ispconfig For the sites which are not allowed to use the php5-cgi with the suphp-mechanism, i use php5 as a module as well. For that sites i've put some extra directives within the directives field within ISPConfig, like these: suPHP_Engine off RemoveHandler .php php_admin_flag engine on This works fine, however for compatible reasons, i need to use php4 as a module in stead of php5. My question is: Which steps do i have to take to use php4 as a module with php5-cgi+suPHP in stead of php5 as a module with php5-cgi+suPHP ? Thanks in advance.
