owengreaves Posted July 22, 2015 Share Posted July 22, 2015 I got this error on first attempt to upgrade, here is what I did to fix it: - Log into cPanel - Go to MySQL Databases - Remove "Privileged User" from the whmcs database - Add the privileged user back in again (same username and password as before) - Then assign user to the database again You should be able to continue with your install. Good luck! 0 Quote Link to comment Share on other sites More sharing options...
