XF 1.2 Responsive Design not working after upgrade


Active member
Hi all-
Yesterday I upgraded my old version of xenForo to the latest version.
The upgrade went well, and file check said all 1096 files were there.
Everything seems to work except when I look on my iPhone or scale down on a browser, the site does not adjust the width to match the screen even though the right nav goes away.

Any suggestions on how to fix this would be appreciated. Thanks in advance.
