Sometimes when I reload my server one of the item frames does this http://i60.tinypic.com/2qb6ohk.png And I can't remove it. To get rid of it I have to remove all entities which is a pain. How can I fix it?
Not sure how to fix it but as long as you have Essentials you can do "/remove itemframe 1" to remove all item frames within 1 block of you. Just make sure you're right up against the frame when you do it otherwise it won't be within 1 block of you!
Maybe try spilling water over it. Could possible work, or maybe using WorldEdit could remove all blocks within that radius, try as much as you can.
