Hi,
Just updated to 3.7.15. Everything except my header updated. If you look here, everything above the main content is gone in 3.7.15. (Because I get a fair bit of traffic I've gone back to 3.7.9 so the header is there now.)
I copied my header image to the image folder. It looks like the customized code in the header area, bar style etc. updated. I don't know why it's not there.
Your help is much appreciated,
Chloe
