I just made a thread here https://www.physicsforums.com/showthread.php?t=399124 and now whenever I try to use latex to create a new thread I get the same latex stuff from this thread I linked. Here for example [tex]lol[/tex] [tex]a^2[/tex] [tex]\sup[/tex] [tex]hi how are you[/tex] and what I typed for each one is [.tex]lol[/tex] [.tex]a^2[/tex] [.tex]\sup[/tex] [.tex]hi how are you[/tex] (without the dots of course). So why is it repeating the same things from my previous thread? I tried restarting my computer and logging in and out but it still does it. Help me fix this please. Edit: Hmm now after submitting this thread I see that my preview button is bugged because it did not look like this when I was previewing it before I posted it. Anyways, could you tell me how to fix my buggy preview button?
