Embedding Youtube on DMS item

Hi, I tried to embed youtube video in the description field of my DMS document, but the tag iframe is always stripped. I've tried to switch the WYSIWYG editor to CodeMirro even to NO WYSIWYG but the tag iframe is always stripped.
I also have checked the text filter permission in the Global Configuration and that's all fine, I have the permission to insert iframe inside the document.
I also tried to add the iframe to my joomla article and it works fine so I assume this is something related to dms. Can you check it please?

Hi

Please try the solution below :

1. Open the file administrator/components/com_dms/controller.php

2. Find the function save_document

3. Inside that function, find the code below :

4. Change it to :

$post = JRequest::get('post', JREQUEST_ALLOWRAW);

After that, the issue should be solved .
