Joomla 3 can't add to article

Joomla version: Joomla! 3.3.6 Stable [ Ember ] 01-October-2014 02:00 GMT

I want add js script to one my article. I'm using TinyMCE editor to edit article.

In TinyMCE plugin field Prohibited Elements I filled with dummy text, now it contains "cms123", I removed "script,applet,iframe".

I checked Global Configurations -> Text Filters for Super Users I have set it "No Filtering".

But when I'm trying to save my article with js code, joomla removes my tags <script> from my article, also I checked with <iframe>, joomla replaced this tag with <i-frame> tag... I'm really confused, I can't understand what is wrong.

Can anybody help me?

Thanks.

Actually, i spent 4 hrs to find out this issue and got solution now. just login to administrator then go to System-->Global configuration, under that you will see "Site Settings", in that you will find-out "Default Editor", select as "Editor - CodeMirror" and save it. after that go to articles, then add your script. Enjoy :)

I just came across this problem today and I confirm the same problem. I could not remove the "script" prohibited elements but I was able to remove everything else. I then tried just putting a period in the Prohibited Elements input box, saved and I now can use script tags. I frames work too. I'm using 3.3.6. Strange.

Global Configurations -> Text Filters for Super Users - set it "No Filtering"
Users -> User Manager - Make sure you have Super User privileges
Extensions -> Plugin Manager -> Filter:Editors -> TnyMCE -In the TinyMCE plugin field, add a period in the "Prohibited Elements" field

I've spent quite a while getting to bottom of this - even after installing JCE editor the problem persisted. It turned out that another security component RSFirewall was running inthe background stripping out prohibited elements.

The solution therefore is to add an exception in the RSFirewall firewall configuration: https://www.rsjoomla.com/support/documentation/view-article/785-scrambled-tags-iframe-becomes-i-frame.html

Got the same issue. I'm using 3.6.2. Here are how I get it works:

Global Configurations -> Text Filters for Super Users - set it "No Filtering"
Users -> User Manager - Make sure you have Super User privileges
Extensions -> Plugin Manager -> Filter:Editors -> TnyMCE -In the TinyMCE plugin field, remove "script" in the "Prohibited Elements" field
In "Extended Valid Elements", add "script"

And I'm able to add script tags in the article now.
