Error Message when Logging in on VIZpin.net
If you are trying to login to VIZpin.net to manage your account, and receive an error message that there is an issue loading a Visualforce page (see screenshot below), this is almost always caused by not fully logging out of a previous session. Please try to clear your cache or use a different browser to login.
If that doesn’t work, try pasting the URL https://www.vizpin.net/adminhome and see if it takes you to a logged in area, where you can either logout fully or continue with the action you were trying to do initially.
