Spending the Christmas/New Year break doing some updates and have gone to WP3.8 and Atahualpa 3.7.13

FYI I used your manual update procedure (as I have done before) and have my header images stored in wp-content/ata-images, etc

Website is www.dibdenchurches.org

1. When I switched to 3.7.13 I lost my header images and menu. I switched back to 3.7.12 and it was ok. After a lot of trial and error I removed the <div> bit of this and saved:

<!--This puts the logo image over the header-->
<div class="header-image-overlay"><img src="http://dibdenchurches.org/wp-content/ata-images/Web-logo-small.jpg" /></div>
%image %bar2 %pages

Got the header images back and the menu but not the logo. Didn't know what else to do so pasted the <div> code back, saved, and everything came back as it should be.

Should I have done something else or will I have to do this each time I upgrade?

2. When I'm logged in (v3.7.13) I get the normal black-background bar at the top of the screen when looking at the Dashboard but not when looking at my site (as before). If I switch back to 3.7.12 I see the black bar as I always have. Is this by design with 3.7.13?

take a look at the sticky thread [SOLVED] Updated to 3.7.13 - All Headers and Footers vanished in the New Versions & Updating forum

Just found that the black bar I refer to is called the Toolbar.

3.7.13: In my profile if 'show toolbar when viewing site' is ticked I see just a white space above my site where the toolbar should be. If I deselect it the space disappears.

Thanks -thought I'd done that but did it (again?) and its ok now.

The toolbar is a WP option - it may have gotten reset when you upgraded WP.
glad you have it sorted out, I'll close this now.
