tinymce stripping code though houstons fix applied

Hello

Dolphin 7.3. is running

I applied Houstons fix https://www.boonex.com/forums/topic/Adsense-stripping-again-.htm#262970 

The solution is to add:

                        valid_elements : '*[*]',

to TinyMCE init in /templates/base/scripts/BxBaseEditorTinyMCE.php

Then i cleared all caches in the tool section.

But the editor still strips the meta properties in the article modules when i want to add them in order to share properly images and description to facebook.

Does anyone have an idea?

Any potentially harmful code is also stripped on server side as well. However it isn't stripping it for admin account. So I would suggest to post it under admin account.
