Please provide any additional information below.
From the BigWigs developers: Boss Notes Rules is using the old way of registering zones (), tell the author to fix it for Big Wigs 3.7.

Change in the mentioned file the function on line 22 to read the following:

function BossNotesRulesBigWigsDisplay:OnInitialize ()
	self.supported = IsAddOnLoaded("BigWigs_Core")
	if self.supported then
		self.mod = BigWigs:NewPlugin("Boss Notes Rules", "AceEvent-3.0")
		self.mod.db = { }
		self.mod.db.profile = { }
		self.barTexts = { }
	end
end

It's line 25 that has the real change (if I recall my changes correctly). This will make Boss Notes and Bigwigs cooperate together again.

This problem is _still_ present months later in the new v1.2.7 release in combination with BigWigs r8684 (current build). Identical error to the above on the same line number(s) at logon with both mods loading.

The fix provided by Luckyjack_SL shown below actually solves it. For those who would like more information, the file to put it in is BigWigsDisplay.lua in the BossNotes_Rules folder. To condense the shown fix, just replace the existing line 25 in BigWigsDisplay.lua with:

self.mod = BigWigs:NewPlugin("Boss Notes Rules", "AceEvent-3.0")
