Howdy again Simon,
I appreciate your opening up a second topic for this issue. Like my last response though, I do not see a CSS/positioning problem in 2015 theme. Would you mind letting me know if you switch themes again, and the problem resurfaces? I would love to help.
The find out more issue is a bit unique. Did that go away when you switched themes as well? I bet that it did. That one I might not be able to provide code snippet for. Usually when that sort of thing happens it is a deliberate attempt by the theme author to override the find out more bar.
Please let me know if you have any questions, or if you switch back and the problem resurfaces. Cheers!
