There seems to be a design (CSS?) bug on the main site. Look at this button in the "edit profile" settings:
Here is the corresponding page on a different site:
It's not just that button; I encountered this problem when handling flags using a prototype for a revised flag overlay written by a CM. When I reported the bug there, he found that it's an underlying design bug on this site specifically.
I believe the pattern on other sites is that the text color in the circled box matches the usual button color, and the background color comes from something else on the site. We're not getting the expected background color here.
