When I save an article in dj-classifieds, if in the description I added a video with the iframe tag this is deleted.

I use JCE and I have set everything so that this does not happen. In fact for Joomla! articles I do not encounter any problems.

This problem was not present before the last update made to JCE. After updating in two articles dj-classifieds I missed the videos included in the article description.

How can I fix it?

Thanks
