We are in the process of converting a Customer Portal into a Customer Community and we are having issues with the 404 redirect function of Communities.
Using Customer portals when a user enters in an invalid URL they are redirected to a visualforce error page, this works perfectly.
When we convert to communities however with the same setup the 404 redirect transfers to the standard salesforce page not found error within the Standard Community. This is an issue as this breaks the look/feel as we are using all visualforce for this portal.
Has anyone come across this before or have any ideas of how to fix this? There is the redirection setup within the force.com setup but you would need to know the Url the user is typing, as far as I am aware we cannot do Regex based redirection using that functionality.
