How to stop CKEditor 3.6.3.7474 from stripping  tags With Full HTML enabled and related filters off, CKEditor will strip any &lt;script&gt; tags from content it is editing.  The editors who create content for this particular site need to be able to embed things like this in the content they are creating:

    &lt;img src="http://s2.thingpic.com/images/TD/zKWJQJiFBsp3oP1etNC1.png" width="560" class="alwaysThinglink"/&gt;
&lt;script charset="utf-8" src="//www.thinglink.com/jse/embed.js#286861458501795840"&gt;&lt;/script&gt;


In theory we can make this work by disabling CKEditor and working directly with HTML, but in practice it doesn't work: the editors are not HTML-savvy.  They know enough to temporarily drop out of rich-text mode, paste in the above, and then switch back to rich-text mode.  But if they go to edit that content again, CKEditor strips the &lt;script&gt; tags when opening the content.

How can I stop that behavior and have CKEditor leave the &lt;script&gt; tags in place?  Is there a hidden setting somewhere for that? 

BTW, we are using CKEditor in conjunction with Wysiwyg 7.x-2.1 module.

And yes, in general allowing &lt;script&gt; is very bad, but in this case the only people who have access to the Full HTML format are the editors (who are trusted).

Thanks!
You can resolve this by going to the "Advanced Options" section of your CKEditor profile and adding the following string into the text area:
config.allowedContent = true;

This resolved the issue for me.
