Hi, After updating to the new version of Wordpress, I can no longer edit blocks on the page. 

I click on the edit button but nothing appears.

I followed your guide to update the theme.

My website: lovoil.it

Thank's in advance

Hello,

Is there any error message?

Also, did you try to disable all of the plugins, and check, if it started to work?

thanks

No errors.

It's a site in production. Tonight, I try to disable all plugins.

I installed the plugin "Enable jQuery Migrate Helper by The WordPress Team" and now the Muffin Builder works
