I get this error when I try to search for a post by name in the backend (under custom post types)
Warning: Illegal offset type in isset or empty in /home/tro_admin/tradereadingorder.com/wp-includes/post.php on line 811
If I try to search again from that page, it shows a blank page with "Invalid post type" in the middle. I can back up a couple times and search again, but I get the original line 811 error again.
Any ideas? My post types are registered in the functions.php and I don't seem to have other problems (that give an error anyway)
