Thank you!
I managed to find the solution. It is Avery theme and built with Elementor.
The solution (if anyone else needs it or if I forget) ??
While in elementor I was always changing the settings for text – typography.
Everything was set to ‘null’ [/] but inside the body text nothing was happening, it did work with header and footer.
What changed everything was to Edit column!
After I set all to [/] in Edit column text and typography section all the settings from Avery theme appeared.
