Yes I wiped everything in data/forums. I did it exactly how long post told me to do it.
I believe I found the problem but give me a moment.
I have figured out the problem. Some users might get confused when they are typing their message in the TEXT BOX and run out of space so they click the "long post" function without KNOWING that their text in the TEXT BOX will not be displayed. Thus why my first part of the message is gone because it was in the text box.
I already have had multiple users get confused with the text box not adding to the message with long post.
I think you read part of my message wrong because I wasn't concerned about getting rid of the posts. I already had told my users old posts were deleted because of the update.
I was just giving you info on how maby you should fix it so that if they typed a message already in the text box it gets added before "LONG POST" and maby change long post to "Continue Message" or something like that... Unless this way isn't possible, which I believe it should be possible to do.
