Log in/log out from a forum with "script" in its title redirects to 404

Hi,

We noticed one weird problem. We have two forums, when you visit it as a guest, then logs in, you are redirected to a 404. The same happens if you log out in those two forums. The two forums share one common point : they have the "script" word in their title (VBScript and Javascript). In the url after redirect, one erroneous %20 is inserted in the URL before "script", leading to a 404.

Exemple : before login (or logout), the url is :

http://www.developpez.net/forums/f28/autres-langages/general-visual-basic-6-vbscript/

after login (or logout), the url is :

http://www.developpez.net/forums/f28/autres-langages/general-visual-basic-6-vb%20script/

Which gives a 404 error.

It happens for the forum itself, their subforums and the threads inside them.

None of the other forums seems to have problems, so the "script" word in the forum name seems to be the culprit.

We're using VBSEO 3.2.0 Gold on vBulletin 3.6.10 PL3.

Any idea to solve that weird issue ?

do you have mod_security enabled? this sounds like a typical issue with it...

No, our Apache only uses libphp5 and mod_rewrite. Our Php is using xcache as php cacher, there is nothing else special in our server configuration.
