I have the an issue when I trying to delete by custom taxonomy. Doesn't matter I have 3 or 200 posts in it, any post isn't deleted.
I had no wait time after clicking in delete button, it sais me 'Deleted 0 posts from the selected custom taxonomies' inmediatly, no php errors or whatever.
I can't find out a solution for this. ¿Maybe my wordpress version (3.5.1 and plugin is latest version)?
