You can try to recheck if you have properly selected the wide format for default layout, pages and posts. If all are selected as wide format, you can check the individual posts or pages if they’re layout are accidentally set differently (layout options selected on each page/post override the general design settings of the theme). If you’re still having trouble, you can also try to check your widgets and try removing those that are located on the right sidebar.
Hope this will help you. If not, then I’m sure someone else here will be able to. 🙂
This doesnt appear to be fixed. I have this same issue. I tried to change the size of the content and sidebar (i want the sidebar to be wider anyways…(300px) and changed the width to 25% and the content to 72.xxx respectively (added the two default percentages so that the total width wasnt effected) but it caused the mobile site to break.
How can I change the widths of the sidebar and the main content to where it will still be responsive?
