@Tom-Riddleff That is quite weird. Would it be possible for you to provide us a copy of your database so we can investigate the problem?
Move post, first from topic
very often on my forum people are starting new threads, and I need to move the starting post to already existing thread.
But I can not, is it possible ? or we can move only next posts ( replies to thread )
From a category view (list of topics) you can go to tools -> merge to merge new topics into old ones.
