I've got a strange problem on my installation of mediawiki (an extra blank line is emitted as the first line of all pages from my site). This apparently breaks the RSS feeds.
Can anyone suggest a good way to debug where this newline is coming from? I was hoping I can run index.php from the cmd-line, and then at least be able to figure out what's happening here.
Interestingly, I made a second copy of the wiki software in which I've been hacking in trying to debug this, and there, I see my shell prompt as the first line of text. So, something's pretty obviously shelling out during init, but I've currently got no idea what is doing that.
thanks, -Nick
