I'm running multisite on WP 3.0 with DH and I noticed all of my sites were loading blank pages. Switching to debug mode uncovered a ton of errors including "is_site_admin is deprecated", "is_taxonomy is deprecated" along with a ton of other "function.php" and "template-tag" errors.
Switching to twenty-ten resolved all errors. I tried disabling all plugins, reinstalling a clean version of the P2 theme and just in case, reinstalling all new wpadmin and include files. Still get the errors.
Anyone having the similar issues of blank white screens on new sites or these other errors with P2 on multi?
