SOLVED Strange Bug Causes Code Insertion

[Arugula]

Well, today I moved to a new, clean server on a VPS and freshly re installed.   But, the same bug reappeared!   I changed the theme and dectivated the plugins, but this did not help, the bug re-appears.  It seems to be that CKeditor itself is causing this code injection.   However, my CKeditor is only that which came with fresh install of Getsimple version  3.3.13.    so I'm confused.  
For the moment I can use the workaround of the 'fake div', but it is disconcerting.
