A few of our users have started getting the below error message when logging in. They are all on IE11 and we have checked the compatibility view settings and everything looks fine. We have just started getting this on a few users and suspect it is a setting in their network profile but do not know what to check for.
ERROR: TypeError Number: 5007
Message: Unable to get property 'errorMessageBox' of undefined or nul; reference
Description: Unable to get property 'errorMessageBox' of undefined or null reference
Function: loadStorage
File: object/PortalConfig.js
It looks like they don't have access to the .js file for some reason. Maybe an IE security setting or something? Any ideas?
