If you haven't installed a 3rd party certificate, your guest users will see a certificate error because the wlc uses a self signed certificate. If your on v7.2, I believe that's the code this feature was introduced a, you can disable https for web auth. This way you don't get a cert error.

the real workaround is disabling HTTPs, and SSH (everything related to certificates) then save configuration and then a reload is a MUST.
