Admin and Moderation Log errors

[skb]

Since upgrading to 2.1 RC3 I find that the Admin, Moderation and Ban Logs are not being updated. The logs are populated up to the date of upgrade. Prior to this, while on the RC2 (nightly builds), all the entries are there in the logs.

There is just one exception. One edit to Permissions of a group is there in the Admin Log.
