I was going to suggest renaming you’re plugins folder, you’ve done that already.

Try renaming the directory of your theme, or the entire themes directory if that doesn’t work

Strange, I tried hitting some URLs direct, e.g.

• http://restomod101.com/test/wp-admin/edit.php?post_type=page
• http://restomod101.com/test/wp-login.php

I’d also suggest taking a look at any custom functions you have in a functions.php file

What about rewrite rules, have you any custom rules in your .htaccess file?
