Upgrading vB with vBSEO, blank pages, help!
 

I just tried to upgrade from 3.8.4 to 3.8.6, but the upgrade.php page and index.php, etc. pages of my forum are BLANK when I visit them. Should I have disabled vBSEO before upgrading vB? I can't even get the vBSEO settings page to load now. All I get are blank pages, but my vB Control Panel does load. Can I disable vBSEO? Help!!!
