I hope you are well today and thank you for your question.
Are you getting any errors when you try to use it?
Could you please share the screenshot of the issue?
Also, would you mind if I log in to your site and do quick troubleshooting? If this is ok then could you please temporarily create an admin user account and share the account login details privately by adding them in the box having text “Enter your private content here (only you and forum moderators will be able to see it)”?
I tryed with firefox and chrome, but with the same result.
it is a strange behaviour, I start a new page called prova and I have the page in the attached screenshot:
if I click on “aggiungi elemento” button nothing happens,
if I click on “add text block” button it adds a text block, but I do not understand why..
