[delpot]

i believe this occurs when there is a thread that has deleted posts.

the original post count went to say page 7 but the edited version is only 6. it seems a bug occurs on the main forum screen that indicates the thread is still 7 pages long. when the user clicks to go directly to page 7 (which no longer exists) this message happens.

try going to an earlier page and it should work up to the last non-deleted post.
