I have not looked at this in a while but I recall an option for mobile as to where to stack the info from the sidebars. I fear that stacking the sidebar for mobile is not working as I do not think the page ever loads fully. I do have expensive pages due to ads. Has that option gone away and is not fully integrated into the mobile design?
Thanks
Read below for the various Sidebar options. These can be set globally for each page type, and overridden locally in any given page using the page editing page options
