Hi! I recently discovered this plugin and it's exactly what I need. Thanks so much!
I just stumbled on some strange behaviour, though, and I'm not sure if I did something to cause it or if it's a bug.
When I view all posts in the admin panel, I can search OR filter by category without issue. But if I search the posts and then filter by category, I get a blank page with "Invalid post type". I deactivated all plugins to make sure WP wasn't doing it on its own (it doesn't). I also deactivated all other plugins to make sure it wasn't a conflict between plugins. I'm using the Twenty Eleven theme, but I'll be using a custom one eventually.
To be honest, this is such an unusual case (for me) that normally I wouldn't bother posting about it, but I know my clients, and they will stumble across this too. I'd just like to find a solution before they have a chance, haha.
Any ideas what might be causing this? Thanks in advance!
