@Burt and Jeff: thanks for your help…

… I’ve found the solution to this one:

I was using the switch_to_blog() function to retrieve posts to display in a header bar, and had neglected to call restore_current_blog() at the end.

It was somewhat unexpected that this would cause links in profile fields to be amended. Is there any reference manual for the bp functions? Or anything planned?
