Hello team, I am building a site with newsberg.
I first created a new site with Quickstart Joomla3, to have the template complete with demo data.
Now, after backup, and after importing several articles, I wanted to migrate it to joomla 4.
But after migration I get this error in home page and the site does not work anymore:
Class 'FieldsHelper' not found
The backend is working normally. If I change the template, from newsberg to cassiopeia the site works.
I have also tried reinstalling newsberg x j4, but it still fails.
Can you give me some indication?
