Hi,
We sporadically experience the exception below, which ruins the main page. The exception happens when navigation is trying to run through the groups set up on a specific page. It happens rarely but when it happens it is critical (2 times today). The error also seems to persist, so my guess this is something that is cached wrong.
Anybody else experienced this?
