when i post it doesnt always show up
when i make topics it doesnt always show up.

and the chat box just goes blank for awhile.

is there anyway i can fix this?

chat box goes blank if you don't post in if for a short time, or there has been no activity in your window such as clicking links. Apparently, you're posts are showing up just fine, though if improper or spammy, they may be deleted by mods.

is it possible that you are hitting the "back" button? i have noticed that posts i have posted dont show up if i hit the back button after posting.
and {usually} the subjected posts in question were legit.
