I understand that some of the immunities/resistances for the Petitioners in Manual of the Planes are incorrect. Anybody know where I can find errata for this book?
Planescape, Dungeons & Dragons, their logos, Wizards of the Coast, and the Wizards of the Coast logo are ©2008, Wizards of the Coast, a subsidiary of Hasbro Inc. and used with permission.
The errata is here:

But it doesn't have what you are looking for. What you need is the accessory update booklet found here:

Enjoy!
