Hi, I have correctly configured the plugin to use SP PAGE BUILDER within the Joomla articles. In fact I see the edit button inside the articles, but when I save them, they remain with the contents of the standard editor.
Attached are some screenshots.
In the first I have selected the SP PAGE BUILDER tag,

in the second, after saving, we notice how Joomla takes into consideration the other editor again.

Hope you can help me. Thanks
