Is there any specific place in Wow you get the error? (in an instance or raid for example) Or when you do some specific action?

Thanks for the help!

seems solved

So sorry to necro this, but it's not actually solved.

The issue stems from dual-wielded artifact weapons. When I log in my Priest... if I was in Discipline or Holy spec (each wields a staff), then there is no issue. But if I log in as Shadow spec, there is a "hidden" offhand that goes along with the dagger. There is no actual Item per se, because it only takes up one inventory slot -- but it takes up two equipment slots (main hand and off-hand). This is why the GetItemLevel returns nil and the max function can't compare your mainhand iLevel to it. The same holds true for my Demon Hunter (in either spec, a single-Item Artifact weapon uses both equipment slots) and my Rogue. In each of those instances, I get the above error when logging in.

I was able to temporarily fix the problem for myself by changing line 94 to:
if itemLinkOffhand then itemLevelOffHand = itemLevelMainhand end
