[Plugin: Simple 301 Redirects] Delete a redirect?

If you clear out a row (both the request and redirect field) and save that row will be gone.

If your redirect loop is preventing you from getting into admin you can clear out the data via mysql (using phpmyadmin or similar) by clearing the 301_redirects entry in the wp_options table. This will clear out all of your redirects, however. If you want to remove just one entry via the database you can do so, but be careful to preserve the wordpress option serialization format.

Hope that helps!
