Just upgraded to WordpressMU 3.0 last night and when I attemped to export a form's entries I got the error message: Unable to download download.php from (the main site's url). Unable to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later.
WPMU 3.0 did make some major changes, like ditching the blogs.php file. I'm guessing it's tied into to that.
Any help would be much appreciated it.
