but it deleted the post OK

edit: that was and "old" pm, so the "error" may be related to the postee entries (?)

It might be, not sure

Were you deleting a message in the outbox or inbox? Did you press the delete image or from the drop down box to delete multiple messages?

options-->delete from inbox..

I just tried it with an old and a new message and i got the error too, looking into it now,

Fixed!
