I read up in the forum about the issue of missing sidebars the upgrading to WP4.4 (which happened yesterday), tried changing the code on the single.php but it did not work. Downloaded and installed the latest version of Cardinal but my sidebars are still missing!
I was able to make one page work by dropping the content down to 2/3 of the width and putting in a widget area to the left where I was able to show sidebar widget content, but that is not a feasible solution as all of the posts and many of the pages have sidebar content on them.
Help!
