Okay, I've searched the forums, tried some fixes, and nothing is doing the trick.
I have WordPress installed at http://www.ycc-inc.org/wp/ - I had a 301 redirect from the root directory, but switched to the method described here: http://codex.wordpress.org/Giving_WordPress_Its_Own_Directory
...except I can't access the .htaccess file from the /wp/ directory. I also tried updating permalinks. Despite all this, I can get into the wp-admin area but continue to get this error:
The page isn't redirecting properly
Firefox has detected that the server is redirecting the request for this address in a way that will never complete.
* This problem can sometimes be caused by disabling or refusing to accept cookies.
Any ideas of what else I can do?
