Listed author links (permalinks problem?) not working

Hello, I recently added another writer to my small blog. I am trying to list our names, and corresponding article counts, on the sidebar. This hasn’t been the problem, I’ve used the wp_list_authors function:

wp_list_authors(‘optioncount=1&exclude_admin=0&show_fullname=1’)

The problem is actually the links that are generated with the code. On my local development, everything is fine with the links formed like this:

../?author=1
../?author=2

But on my live site, where I have permalinks set up, links like this:

../author/bobby-mcgee/

result in Firefox telling me:

“Firefox has detected that the server is redirecting the request for this address in a way that will never complete.”

I don’t know if it’s a problem in my permalink structure? Article links themselves have generated without a problem thanks to this custom structure:

/%year%/%monthnum%/%day%/%postname%

but I don’t even know if that tampers with the author’s links. Anyone know what my problem is off the top of their head? Or have an idea where to look? Thanks!
