Error at login, I think it comes from ClassTimer (using v2.4.90001.1):

same error

and when I use classtimer and addonskins, there would be an error like this

buf if i only use addonskins, there is no error

Error still there with Version: 2.4.90001.1

Zorcan2112 posted a fix in the comments, which works for me:

I was getting errors with the Shadowlands Alpha when logging into a character referencing PLAYER_PET_CHANGED. I managed to fix the issue by updating line 342 and 361 of Classtimer.lua

 

Old:

Line 342: Self:RegisterEvent('PLAYER_PET_CHANGED')

Line 361: function ClassTimer:PLAYER_PET_CHANGED()

 

New:

Line 342: self:RegisterEvent('UNIT_PET')

Line 361: function ClassTimer:UNIT_PET()
