Editor on submit question page not working

The reasons could be
a) What you might be seeing is cached pages of WP 3.8
b) I upgraded to 3.9 after that
c) The following is the error from TINYMCE :

Deprecated TinyMCE API call: <target>.onKeyDown.add(..)
I’m using MINIFY tools and tinymce.min.js is excluded from MINIFYING :
The file location is :
/wp-includes/js/tinymce/plugins/compat3x/plugin.js

This means one of your other plugins (or theme) is using an outdated function name. They will need to update their code.
To find the faulty plugin/theme.. please read this topic:

As I can see from this page (i.e, http://cmspioneer.com/designwall/question/editor-on-submit-question-page-not-working/), looks like, TINYMCE is not updated to the latest version, i.e, TINYMCE 4.0.
Error is coming after upgrading to the latest version of TINYMCE 4.0.1

Looks like there is a conflict with ‘WPSC Support Tickets’ plugin.
I used PLUGIN ORGANIZER to disable all plug-ins NOT required for DWQA pages (including ‘WPSC’ plugin) and editor showed-up again.
PLUGIN ORGANIZER is a great plug-in to check plug-in conflicts, enable/disable plug-ins on per page/post basis. In-fact it is a great tool to speed-up the page loading by 2-3 times.
Thanks for the help.
