Plesk 10 500 Error even with only index.html file
When you have a index.html file in the httpdocs folder and still get a 500 Error using plesk 10, try disabling error documents.
Login to plesk control panel
- select Website & Domains
- select Advanced Options
- select Website Scripting and Security
- unselect Custom error documents and Click Ok
Hope this helps some one in the dark side on plesk.
