Well after more digging i managed to fix, not sure if this gonna be a reaccuring issue as noticed in the FckhtmlEditorProvider\custom\fckconfigsecure.js references to 'UniversalKey' example...
FCKConfig.ToolbarSets["Default"] = [
['DocProps','-','Save','NewPage','Preview','-','Templates'],
['Cut','Copy','Paste','PasteText','PasteWord','-','Print','SpellCheck'],
['Undo','Redo','-','Find','Replace','-','SelectAll','RemoveFormat'],
['Bold','Italic','Underline','StrikeThrough','-','Subscript','Superscript'],
['OrderedList','UnorderedList','-','Outdent','Indent'],
['JustifyLeft','JustifyCenter','JustifyRight','JustifyFull'],
['Link','Unlink','Anchor'],
['Image','Flash','Table','Rule','Smiley','SpecialChar','PageBreak','UniversalKey'],
['Form','Checkbox','Radio','TextField','Textarea','Select','Button','ImageButton','HiddenField'],
'/',
['Style','FontFormat','FontName','FontSize'],
['TextColor','BGColor'],
['FitWindow']
] ;
FCKConfig.ToolbarSets["DNNDefault"] = [
['Preview','-','Templates'],
['Cut','Copy','Paste','PasteText','PasteWord','-','Print','SpellCheck'],
['Undo','Redo','-','Find','Replace','-','SelectAll','RemoveFormat'],
['Bold','Italic','Underline','StrikeThrough','-','Subscript','Superscript'],
['OrderedList','UnorderedList','-','Outdent','Indent'],
['JustifyLeft','JustifyCenter','JustifyRight','JustifyFull'],
['Link','Unlink','Anchor'],
['Image','Flash','Table','Rule','Smiley','SpecialChar','PageBreak','UniversalKey'],
['Style','FontFormat'],['FontName','FontSize'],
['TextColor','BGColor'],
['FitWindow']
] ;
FCKConfig.ToolbarSets["NoGallery"] = [
['Preview','-','Templates'],
['Cut','Copy','Paste','PasteText','PasteWord','-','Print','SpellCheck'],
['Undo','Redo','-','Find','Replace','-','SelectAll','RemoveFormat'],
['Bold','Italic','Underline','StrikeThrough','-','Subscript','Superscript'],
['OrderedList','UnorderedList','-','Outdent','Indent'],
['JustifyLeft','JustifyCenter','JustifyRight','JustifyFull'],
['Link','Unlink','Anchor'],
['Table','Rule','Smiley','SpecialChar','PageBreak','UniversalKey'],
['Style','FontFormat'],['FontName','FontSize'],
['TextColor','BGColor'],
['FitWindow']
] ;
I just removed them out and seems to have fixed. I checked fckconfig.js and seems clean from them so presume as my web.conf before was references custom settings to fckconfigsecure.js it was still picking up the 'UniversalKey'
If me removing them out is gonna create probs later on can ya let me know. Or if will need to change every upgrade.
