I have just ran into needing SSI, and it is not an option on our server - as in it;s greyed out on the page to enable it. I checked and it's enabled in IIS Management and I even did a reconfiguration of Plesk and made sure it was installed, and it was. Still I can not select it an no .shtml or such files will run on the server. Any help please? I know it was this way with the fresh install of Plesk 7.5.4 and still after the upgrade to 7.5.5. I am running Windows 2003 with SP1 installed.
