umm, if I may try to help: using Chrome...clear out all cookies, history..etc..clear out cache. See tools (tool symbol) on the upper right and go to 'settings'. Under 'data privacy' hit 'clear browser data' and delete all. Also follow second link here and delete all cookies.

Sometimes it's an overloaded cache or corrupt cookies causing problems.
Hope it helps.
