essefit on "WP Not letting edit & does not display anything in "Visual" mode when editing"

To Whom It May Concern:
When I add a new or try to edit an existing post it only lets me to edit in "text"" mode the visual is just blank. When I try to preview it does not do anything just opens a new page and its blank: (here is where it attempts to take me: http://essefit.com/remote-login.php?login=4fb82b50d931bf360b8754534a6fefd1&id=31214287&u=c62b51ad11f93866017364361d0046be&h). no errors nor nothing. I tried to log out thinking there is a permission issue but nope. Nothing helps. And this is happening since yesterday. Everything else works fine on my MAC just when I log in WP does not display the editing of the post content in visual mode. It is just blank.
