CMS vB CMS Admin CP says I don't have permission?
 

I have a forum setup and I've uprade from vB Beta 4 -> Gold.

Since I've done so* vB CMS category in Admin CP is throwing permission errors:

Quote:
Sorry* you don't have permission to access the administrative controls on this page.

If you need to access this page* ask your lead administrator to enable your permissions for this page using the Administrator Permissions section of the control panel.

I am the only admin* and I haven't changed any of my permissions* the Admin Perms page confirms I have the relevant permissions for CMS administration. From the front end* I can promote posts and such to articles* but I can't create content without first promoting the post* then editing it.

No modifications have been installed on the board whatsoever.
