Hi Rashida,
I use the template Shaper Helix 3.
I get the same configuration as explain in your link. But if "show intro text" is not active, the content of the article don't display. Only the title - meta data - and button Read More.
If Intro text is active, I see the text (characters numbers), but the text is formated in raw text, all HTML tags are delete.
I need this Addon to display Joomla article inside Page Builder.
The URL of the page was in restrected access, I swith it to public.
Thank's for your help
Magali
