I'm using Twenty Fourteen (with a simple child theme) and I'm pleased with it apart from one fairly major issue.
When I add any content to the Content Sidebar, it appears OK in Safari but not with Firefox, Chrome or on my iPad. All that shows with these is the Links Widget which appeared in the Content Sidebar when I activated the theme.
There is also a Text Widget and a Custom Menu which you will see if you use Safari but (on my MacPro at least) not on Firefox or Chrome.
Can anyone help me with this please - I'm completely baffled.
My child theme only controls text size and colour and the size and positioning of
<div> content. It also eliminates hyphens - but the issue was present before I added that.
