Forum powered by vbulletin showing in google search! how to remove
 

I just updated to vb 4.2 and I found the powered by vbulletin in google search, while it should be "Forum" or something else...

I double checked phrase manager x_powered_by_vbulletin and already been changed to {1} many years ago.

so please tell me what to do to let google show my forum instead of powered by vb.

I am so tired...
