Have you tried site layout settings ? That may be set to full width, kindly check those settings and let me know if that works for you ? For settings you can follow documentation.
Ok, I changed the layout setting from full-width to boxed and it didn’t really do anything from what I could tell. I also set the page and container width setting to 800px just to see if the layout changed any but it didn’t look any different. I didn’t mess with the percentage widths. Since I couldn’t see any difference, I reset them back.
I can see you are using child theme. Kindly try to use parent theme and then see how things go ? If that works fine then it means something is wrong in the child theme and it will help to find the issue.
I switched themes and it looks like it’s working. I want to use a child theme so the main one can be updated without erasing the changes I want to make. Do I need to copy some files/folders over to the child directory to be able to customize it how I want?
Then it means the issue is in child theme. Try to use latest child theme which came with package and see how things go ? If all geos fine then you have to fix the child theme issue which is causing this issue.
