edit template not working

[troy]

Hello all,

I am using Links Engine 2.0 By: Gossamer Threads.
I have a strange thing going on, I can edit all my templates except my home template.
When I make a change and want to save I get this message:

The server encountered an internal error or misconfiguration and was unable to complete your request.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request

Anyone know what might be wrong?

Thanks in advance
