I have a domain which references an application on the system that serves out php pages. it resides under /usr/share/webapp . Php works perfectly fine under my users accounts and any php under the web directory of the client works fine. However when the alias is invoked the php page downloads as if nothing was configured :/ I've tried adding : <IfModule mod_suphp.c> suPHP_Engine on # suPHP_UserGroup web2 client1 AddHandler x-httpd-suphp .php .php3 .php4 .php5 suPHP_AddHandler x-httpd-suphp </IfModule> to the alias directory but I still get the same result... If I configure the site outside of ISPConfig control it'll work perfectly fine but I didn't want to do this as this app can be used by more than one user and it'll defeat the object of using ISPConfig. I know I've missed something obvious but can anyone help here?
