I'm using magic fields to create some custom post types. All my custom post type permalinks reveal a 404 not found error. I'm ruling out an error in the way I set it the custom post type up because I can get it to work on a fresh WP install on my local drive.
I've tried re-saving my permalinks structure in the admin. I've chmod my .htaccess file to 666.
I have both single.php and single-xxx.php (where xxx is my custom post type name)
Thoughts on what to try next?
