Forum Friendly Url's
 

Hello,

i upgraded to vb 4.0.8 pl2.At friendly url options after the upgrade it has by default "Basic Friendly URLs". I changed it temporary to "Advanced Friendly URLs", then i move it back to "Basic Friendly URLs" and when i try to access any forum section i see this "Invalid Forum specified. If you followed a valid link, please notify the administrator". If i set i to "Advanced Friendly URLs" everything works fine. Any help?

Thanks
