Hi
I am facing the similar issue, is there any any solution of this?
Earlier I faced facebook depricated permmission issue, later I changed its core file and changed permission then I start getting this issue.
After verifying facebook account it gives broken page on following callback
http://crmsite/index.php?entryPoint=retrieve_dash_page&code=xxxxx
following erros are in console
Uncaught ReferenceError: YAHOO is not defined
at sugar_grp_yui_widgets.js:2
dashlets.js:38 Uncaught ReferenceError: SUGAR is not defined
