Admistrators are Frozen

I can open Cute News, but as an admistrator , I cannot do anything, approve, add , delete etc.  We have 3 Administrators and non of them work.  We have users uploading info, but nothing shows when we go in.  It was working fine  and now I am at a loss.  I am not a developer.  When I asked for help they replied it "seems that the problem consists in the chmod access rights. Please, check it."  I have no idea what I am checking for , I don't even know where to look, I search my computer for "chmod" and nothing comes up.....please help me get my sanity back!
