Well, this is another thing which does not affect Prosilver. I think you need to rebuild the Chronology theme from the new Prosilver rather than trying to patch the old one. (Before I checked this and realised, I was going to suggest forcing an absolute rather than relative URL for the CSS <link>s in the header, but...)
Somebody, thank you for the insight, but Chronology is not a patched theme. It is a child of Prosilver. It only contains 4 files, all of which are necessary for customization.
1. style.cfg
change made to identify the name of the style.
The parent is Prosilver (no change needed, because the parent of Prosilver is also Prosilver)
2. colours.css
change made to the html body element to display and position the background image (cover of FF@ 2)
3. overallheader.html
change made to add a link to the site name, to point to the home page
4. overallfooter.html
change made to add the navigational links to bottom of every page, to point to every page on the site
The images directory contains two files: one is an added file (the background image), the other is a replaced file (replaces the php logo with the site logo).
That's it. Those are the only files in the Chronology theme. The forum inherits all other files, images and styles from Prosilver. And all of the four edited files are the 3.3.3 versions of Prosilver.
Chronology is not a "patched" theme. The old Chronology theme doesn't exist anymore.
Your experimentation has pointed out that since Prosilver doesn't have this problem, the problem most reasonably lies in the Chronology template, but you do me a disservice when you accuse me of simply dropping an old version of the template into phpbb.
(Now there's also a problem with only one of the two unread icons showing up on the topics view page, but I'm not as concerned with that one, since it's mostly cosmetic.)
I've completely disabled the Chronology theme, until these issues can be worked out. This means we lose the navigation links at the bottom of the pages, but...
