Same here, In WOTLK.

Get it on login each time, by the way.

Are you on classic / BC / Wrath by chance?

Not OP, but I am getting this same error in Wrath.

I do not play in an arena team. I an not in a group when this happens. It happens on every toon I have including low level ones. The 427 solution is no solution and not relevant.

I love this addon, but the error is with this addon. If this keeps happening I cannot use it and will be sad.

This has nothing to do with if you are on an arena team or in a group or your level.
The fix has not been pushed out to curseforge yet, so you don't have it.
If it's still broken when fix is pushed out, I'll take another look

I do not play in an arena team. I an not in a group when this happens. It happens on every toon I have including low level ones. The 427 solution is no solution and not relevant.

If you need this addon to work right now you can manually fix it by copying the code from this page https://github.com/carbohydrate/bigdebuffs/commit/b6b61028c935ec57ba9839555bd0048353c3f9e9

Copy 852 - 853

if k == "Blizzard" then
anchor = type(v.units[unit]) == "string" and _G[v.units[unit]] or v.units[unit]
if k == "Blizzard" and type(v.units[unit]) == "table" then
anchor = v.units[unit]

make sure to keep everything under starting with
else
anchor = _G[v.units[unit]]

Go to the very last line which should now be 2375 and add 'end' (without quotes).

This will remove the LUA error.
