You should install the update, then the problem should be solved. If you run any issue, then please try the nightly build, its on our download page, on the bottom.

Sorry but Iám new hier.

We have the cross site scripting problem. By abusing the vulnerability an attacker can store JavaScript in the database, which is stored in the title of the answer he or she wrote. The now stored XSS is executed every time a user enters the affected topic in the forum, which could therefore be triggered by any user of the system. Note that the XSS gets only executed if it is the latest answer of the topic.

Can you help us?
