new website feedback

I found an issue with thread subjects that were edited. Sometimes the changed thread subject reverts back to the original one, not sure when exactly this happens but I think it might have something to do with posting new posts to the thread or editing old ones.

edit: the same can happen with edited content of regular posts, sometimes the post reverts back to a state before the edit.

I also noticed that when trying to remove attachments via the remove all button, the whole post is deleted and replaced with just a single "1"
