The iframes are removed from the code in some articles but not in all. I don't understand why. The Media setup ist correct like here https://www.joomlacontenteditor.net/support/faq/editor/iframe-content-not-displaying and the Sandbox-Mode is off. But still the iframes will be removed from the code in new Articles in the moment i hit "save". But in old articles the code ist still there. How can that be and how can I fix it?
Thank you
