Yes, it could be something inside the code it's requiring that is
issuing a header. But it could still be an error in the code inside
your index.php page. I'm not aware of anything in MAR itself that can
cause this error.
Try this (it's a good general debugging trick): inside the index.php,
comment out all of the header() calls, and then access the page using
Firebug. Look at the response (in Firebug's Console tab) to see what,
if anything, is being printed to the browser. You may have an error in
there that isn't being properly trapped, although I'm not seeing it if
that's the case.
