I'm stuck. I wanted to install and configure FlexShares, but I got this error initially on the shares screen so I tried going to accounts>Users and encountered the same thing. I am also getting this error in accounts>Groups. I'm really sure as to why this is happening.

A little background info: this system is the same one that I had to install the Sangoma WANPipe drivers on that I mentioned in this thread: here

Some how something rendered my Graphical Console inoperative (X will no longer start). I can still configure the system by either using the web console or logging on to one of the consoles then doing an export DISPLAY (pointing it at another system that I have here) then running xconsole. However, both config methods still suffer this problem.
