1. You haven't hard refreshed the thread it is in. 2. It was deleted because it was spam. 3. It has randomly disappeared. 4. Kittens. Massive amounts of kittens.
Seriously, though, most likely either one or two up there.
Well this happened to me and I was like well can nobody see what I'm writing so I messed up a forum like it apears either hours later or allot of hours later it's kinda frustrating but I learned so I know that it'll give me AP then it'll come up some time later
Sometimes it will work and your post will just show up before you refresh. Other times it will not. I just tend to refresh when I go into a thread to make sure it is showing me the up to date version of it.
Hard refresh. Crtl + F5. Normal refresh doesn't work.
Actually, normal refresh does work, but hard refresh might work better. At least it does for me. If normal refresh doesn't work for you, then why would it only work on some computers?
Theory:
Normal refresh works on some computers. Hard refresh works on more computers. If neither works, AG doesn't work on your computer.
