I have disabled all addons and used only Chatter to verify the bug. The bug happens as soon as you enter any pet battle. I only tried in the Broken Isles.

Seeing the same UI behavior. This bug popped up when I tried to enter a pet battle:

I see all pet battles buttons are missing with chatter loaded. Broken isles as well.

If any of you are confident enough to edit lua files:

It looks like there's been a change with the messageFrame:GetMessageInfo() API in 7.1. Chatter is using:

local text, accessID, lineID, extraData = chatFrame:GetMessageInfo(i, accessID);

The 7.1 default UI now uses:

local text, r, g, b, chatTypeID, messageAccessID, lineID = sourceChatFrame:GetMessageInfo(i);

If you change this at line 37 in Chatter\Modules\AutoPopup.lua:

local text, accessID, lineID, extraData = chatFrame:GetMessageInfo(i, accessID);
local cType, cTarget = ChatHistory_GetChatType(extraData);
local info = ChatTypeInfo[cType];
frame:AddMessage(text, info.r, info.g, info.b, lineID, false, accessID, extraData);

to this

local text, r, g, b, chatTypeID, accessID, lineID, extraData = chatFrame:GetMessageInfo(i, accessID);
frame:AddMessage(text, r, g, b, lineID, false, accessID, extraData);

Everything may work fine.

I don't use Chatter myself. But another was having issues with Chatter alongside one of my addons. So I don't know if this is the best solution.

@Gello: Go

Thank you, this fixed the pet battle issue for me.

Version 1.5.3 appears to have resolved this issue, thank you!

Confirmed here as well. 1.5.3 Resolved issue.

1.5.3 didn't fix it for me
