Like I make a post in a thread so when I go to that section it says last post by "BTK". Then I click on the thread and scroll down to the bottom and it's not there. I press back button and refresh and it still says I had the last post in the thread so I click and scroll down to the bottom and my post is still not there. WTF?
Something could have happened server side when you posted. There is no way we can 'retreive' a post, so you should just try and reposting it.
Might of just been too many connection at that time. Becasue i remember the same thing happened to me. I posted a post and then i click send and it posts it but when i scroll down theres nothing there, but when i refresh i get this white page with a little box saying something about MySQL and too many connections, please try again later. Just a thought.
