I can log into the course, but when try to access any other page I keep getting logged out and I get the Serf Security Error.
Repeated logouts due to Serf Security Checks is usually because of some type of firewall (security) setting on the computer. Your computer may have programs such as Norton Internet Security (Norton Firewall), ZoneAlarm, or any other firewall programs that is conflicting with our course.
We highly recommend you try Option 1 first. If Option 1 doesn't work, please try Option 2.
Option 1: Install FREE Mozilla Firefox browser. Using Firefox usually gets around the Serf Security Check issue without having to disable your firewall.
Option 3: You may want to try to disable your firewall program and see if that resolves your issue.
