Ciao Mario,

But what you see in "SP Page Builder" tab, do you have rows, columns, addons created before save?

This is the most important information for me.

If not, share access to admin area we will check

excuse me, you can see from the attached photo that there are no elements in the SP PAGE BUILDER form, do I need to create them first? from the videos I saw on usage I understood that I just had to save the article by selecting the sp page builder tab and then create the contents from the front-end. In any case I tried both to save without elements in the sp page builder tab, and to save some elements. On saving, any element entered in the sp page builder disappears. I am attaching a video

Thanks for video,

1. But it worked before and stopped working, or didn't work since beginning?

2. Can you disable extra installed plugins and test again, maybe one of them is causing that problem.

3. I hope you have installed the last version 3.8.6, right?

1. It never worked.
2. Which plugins should I deactivate? the plugins that I have active I need in any case.
3. the latest version, 3.8.6, is installed

ad 2) Extra installed one, not from Joomla core (but keep Joomshaper plugins enabled) Just for test period - 3min ... to check if this may cause problems.

is possible to share access to admin area?

I've done some testing and it seems that the conflict is about one plugin, specifically this one:

https://www.conseilgouz.com/en/switch-editor

It is used to quickly change the joomla editor. We use it a lot. Can you carry out some tests to understand if a "peaceful coexistence" is possible?

Thanks
