I have read the documentation for the iframes (https://www.joomlacontenteditor.net/support/documentation/iframes
), but I cannot insert them: they do not appear.
For the Super Users group, the Filter Type of Text Filters tab is set to No Filtering.
Joomla version: 4.2.3
JCE version: Pro 2.9.29
Is there any other option to check?
