I have a new fairly new install of WordPress (1.5, not sure what the latest is out there) and found out my RSS feed is not working.
Using RSSBandit, I get an 404 error.
Through some googling, I found out if I change my bloginfo('rss2_url') value to 'index.php?feed=rss2' it would start working. I've confirmed this via URL too.
So I do I set my bloginf('rss_url') value?
