I've done a bit of research trying to find others that have had similar problems, but I upgraded from 1.5.2 and noticed that a couple of the template tags (partiuclarly included in the template-functions-author.php file no longer work correctly. For instance:
the_author_posts_link('nickname') seems to always return the author post link with the nicename.
I also noticed that other things like:
get_the_author('nickname') no longer work, which I've now changed to use:
the_author_posts_link('nickname'); is the one that I'm having particular problems with, as it's returning the user's login, which does not particularly look too good on my site, for example:
And look at the posted by link at the top. "CoolJesus" is returned, when it should be "Cool Jesus."
I know it's not the end of the world, but I feel as though it's not behaving as it should. Am I incorrect? Has anyone else seen this?
