I've been getting redirect loop errors since I installed WP 2.5.0. I figured 2.5.1 would fix the problem but to no avail. The problem crops up here and there in the admin interface. For instance, in the widgets panel, when I click on "save changes," regardless of if I modified anything or not, it gives me the error.
Some plugins, such as the WordPress Navigation List plugin, don't work as well.
I suspected that there might be something going on with permalinks. I have permalinks set to a custom structure of "/%postname%/". Even when changing to standard permalink configurations, it still does the same thing.
I've tried the normal things like completely removing everything save for my database and reinstalling wordpress but to no avail.
Any thoughts or suggestions would be greatly appreciated. my site is http://www.douglasvanbossuyt.com.
