Last night after posting I got a...
403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request
I contacted my host, who says I probably need to upgrade my index.php file via FTP. I think I can do this, but I want to make sure...because my knowledge of how this works is a little limited...that this won't rewrite my whole blog or anything like that.
Also, where can I get an upgraded index.php file? I've seen similar problems listed here before, but I just want to be extra careful. I do know my version of wordpress is a little old. Might be 2.1.
thanks for your help!
