This stops any of the site content being rendered but the CMS and CONSOLE can still be accessed

Have you checked if your hst:hosts is setup correctly?

Take a look at the grey box.

This is quite odd because it would imply
org.hippoecm.hst.configuration.model.HstManagerImpl#getVirtualHosts(boolean)
returns null. Can you look at the logs *before* you get the NPE? Most
likely something fails during loading the hst model. The logging about
loading the model is quite explanatory and pretty much always telling
where to find the culprit

HTH,
