That "User has exceeded" message is NOT the cause of the following problem, but is likely a result of the following problem:
THE PROBLEM:
When clicking on your link to 3drevolution.org, I am presented with a warning that your site contains malware. And it tells me that the site I'm about to visit is actually named neoffic.com and not 3drevolution.org.
So, unless you put content on your site to redirect to neoffic.com, this indicates that you've likely been hacked in some way.
Perhaps a virus on your computer corrupted one or more PHP files when you attempted to upload them?
Perhaps it damaged some content when you edited a define_page?
Perhaps your webserver has been infiltrated by an intruder.
Regardless the cause, you need to take steps to remove the damage. The following starting point is recommended: http://www.zen-cart.com/wiki/index.php/Recovering_From_Hacks
AFTER you have resolved the problems causing the redirect, THEN you can deal with the "exceeded queries" problem, if it still exists (and probably won't).
