  • [CMS] CMS Error on upgrade to 4.0.2

    The forums and blog work fine but the home page (CMS) shows the error...

    Fatal error: Undefined class constant 'CANON_OFF' in ********/vb/route.php on line 891

    Any ideas please? I have no plugins on and I've re uploaded the files twice?

    That error has to do with the friendly urls. Try changing that option and see if it fixes the issue - vboptions > server settings > friendly urls
