[danbp]

BP 2.0 beta testing with WP 3.8.1 and 2012 theme - local install with php 5.4.12 - mySql 5.6.12 - apache 2.2.4

User message notification on /user/notifications/ page

On the toolbar, the notification count is appearing but not the alert (<li> "You have x new notice (or similar)" is empty).
On the message screen, i have a php error. Warning: sprintf(): Too few arguments in C:\wamp\www\buddy\wp-content\plugins\buddypress\bp-messages\bp-messages-notifications.php on line 130
The string Viewing %1$s to %2$s (of %3$s notification) doesn't translate. (works with 1.9.2)
