Change back to old version
 

Dear all friends,

While I used vbulletin 3.7.4, social group work fine. Now I upgrade to 3.8.0 and social group doesn't work and show database error. And Usergroup.php also doesn't work. How can I fix these problems and do you have any idea to change back my forum version to 3.7.4. Thanks a lot for your answers. I am waiting your helps. :D
