VBSEO no longer working on my site??

I am not exactly sure what has happened... but VBSEO was installed and working on my forum and is now not. It has gone back to displaying the url of each page as it normaly would with VB. I have not messed with anything that I am aware of that would cause this to happen.

Any help?? :(

Thanks in advance

Are you using shared hosting or dedicated? Did the admins make any changes? Have you made any recent changes?

I have a 1 page site on the same account. No changes were made that i am aware of. One minute it was working, an hour or so latter it reverted back to the regular VB pages???

Are you using IonCube or Zend? You should email your host ASAP to ask if they changed anything on the server.

problem solved. copyright show me "unregistered"
Thanks for the help!
