Content doesn’t stretch to full width

Hi!

I’m working with Customify theme and the Elementor builder, and somehow I cannot make the content of my site to stretch to full width. The header and the footer DO stretch to full width, but the content portion of the site just doesn’t, no matter what I do. Can that be because I repeatedly switched themes while building the site – I mean that some old setting is still there? And if so, how does one get rid of that without damaging the site? Unfortunately, I cannot code, so I can’t really fix this problem on my own.

Thanks a lot for any tips and instructions!!
