Since the problem is not duplicable on this site (xoops.org), it has to do with the unofficial modules installed or your set up. I think it is more the first.
To find out which module is the culprit, you would have to uninstall the unofficial modules one-by-one and test F5 key after each uninstall.
Please keep us posted on which module is causing the problem, so the community and the developer could be advised of the security breach. Thank you.
