I have found an issue with the Elementor full width setting and Generatepress.
When I chose Elementor full width (screen 1), my sections are small (screen 2), the width is based on the element inside (screen 3).
No matter what, even if I decided to increase the width of the section, like 1600px, it’s still the width of the element.
I moved to twenty twenty theme and it solved the issue, I can set up full witdh like I want.
Plugin: Elementor + Elementor Pro latest version
Theme: Free Generatepress
