I’m getting this error every time I activate Site Tracking on buddypress.
Warning: Missing argument 2 for wpdb::prepare() called in E:\dev\sites\wordpress\site.com\wp-content\plugins\buddypress\bp-blogs\bp-blogs-functions.php on line 52 and defined in E:\dev\sites\wordpress\site.com\wp-includes\wp-db.php on line 990

I am currently using this setup:
Local Server using WAMP
Multisite setup
Wordpress 3.6-beta3
Buddypress 1.7.2
BBpress 2.3.2

This happened on a fresh install.
I could’ve sworn this was not happening before with the same setup.
Not sure if this is only a beta thing, I haven’t tried it on WP 3.5.1
