It looks like you're using SSI in your Header. Remove the SSI.

How to remove ?? i dun understand ar

My UBB board is on Hypermart but how come my friends' UBB board work well on Hypermart

As I stated, you are attempting to use an SSI statement in your UBB Header or Footer. Remove it.

If that is beyond your capabilities, please post your UBB version and URL.

I need the URL to your UBB, not to a page with half a dozen popups that reopen when you close them. I hate that.
