I have just installed the latest update, which all went fine - however when I try to access the Administrator (which was working perfectly just prior to updating), I get an error which states, "The isAdminClientCertAuthEnabled method was not found."
I have searched everywhere and can not find resolution to this error. If anyone can shed some light on how to fix it, it would be greatly appreciated. Thanks..
I would suggest rolling back the update and see if the administrator is accessible. These kind of issues usually occur if there has been an issue installing the update.
