my vbseo does not working when i activate plugin

my vbseo does not working when i activate plugin and click a forum link or a thread link (after activation of plugin) the page displays message

""vBulletin Message
Invalid Forum specified. If you followed a valid link, please notify the administrator""

 

did you install licence vbseo ?

 

but first it was working i disabled it and now while i am enableing it is not working.
it is not licensed and nulled

 

I think when you enter sub-forum that error massage show.

Change sub-forum name.

Hope it will work

 

My guess is upload, the .htaccess provided?

 

no even main forum, main catogory and threads are also showing same message.

 

.htaccess is uploaded and setted to the setting on wich before it was working.
i think problem is some else???

 

Are you using the default vBSEO settings?

 

yes i am using default settings.

 

Discuss the problem in VBseo forum, They are the best people to help you out.

 

You do NOT realize, he's using a nulled version.

 

so my problem cant be resolved???

 

Ask at the forum where you got the script from.

 

the script was working fine, one day i have a problem that login system was not working, you resolved the problem, after that when i re activated vbseo it was not working.

 

All i did was make sure those settings i pointed out we're correct.

I said ask at the forum you got the script from.
