0 Unable to access Back End Rock System. 1 Brandon Fuchs posted 6 Years Ago I am recieving the following message when trying to access the back end "private" portion of our Rock system. What is causing this and how might I be able to fix this. I am the organizations administrator but unfortunately dont have much experience with the coding and reading the error messages. Also not being able to get into the system makes it hard to understand how to fix the situation. If I need to contact our host I want to be able to be efficient so that the service call fees remain low.
