error
 

i can see this error at the end of every existing thread and while making new thread .. how to remove it plz help

I'd just be guessing, but it looks like you may have been hacked.

Do you did a search in your templates for that specific string to see where the problem may be ?

no i havent found it in templates

Why dont you post a link to your site so we can view the source code.

Create a new style with no parent. Do you still have this issue browsing the forums with the new style?

If that fails please re-upload all the vBulletin non-image files.

well when i disable plugin's it doesnt show up that means its the mod/hack which is causing this

how can i check which plugin/hack is doing this?

enable your plugins one by one an tell you see the error..

If it only appears on a thread then check what modifications interact with threads and save yourself a lot of time.
