I have tried installing standard package, full package and even a custom build of CKE 4.1.1, and iFrames won't work in any of them. iFrames worked fine when using CKE3.
When I copy and paste any iframe source code into the "source" area, then go to the WYSIWYG editor, the iframe is totally removed. Going back to the source, everything between <iframe...></iframe> is totally gone. I've tried installing different iFrame plugins, to no avail. Every time, the iFrame gets removed.
Any sugestions would be greatly appreciated.
Cheers
