I upgraded to mantra 3 and now the sidebars move above the center content area instead of below when the site is viewed on a mobile phone, it appears a global align left may be a the problem. I went back to the older version for now.
How has that worked going back to
2.6?? I want to as well but of course figured they updated for a reason…my site doesn’t work well on mobile after all of the updates.
If you haven’t customized styling or theme files, then we’d need to see the sites with the problems visible to investigate what is going on.
A simple update from 2.6 to 3.0 will not break the layout of the site. It will at most change design details, like spaces/paddings, heights, font sizes.
