You either played around with the settings, or version of vBSEO you have isn't nulled properly.

Install it again, and don't touch anything, if it still doesn't work. It's not nulled properly.
I haven't played with settings, as simply i just enabled it and the problem occured.

Can you provide a completely nulled one. I have googled it and scorched vbteam like for it, but found the same version only.

Thanks in advance.


upload the htaccess provide with vbseo
I have uploaded it at the installation. Shall i reupload??
