I have a weird thing happening. I just updated to 4.0.19. I went to Administrator > Components > EasyDiscuss > Users. I typed a name in and clicked Search and ended up here: http://u-c-m.org/administrator/index.php with a message that read "405 Not Allowed." I clicked the back button and got back to the screen with the search results listed.
Earlier, I tried to delete a post and the same thing happened. The post was deleted, but this behavior jus' ain't right.
