I keep getting

I update my addons every day before I log in.

Closing, no info provided.

Are you just returning to playing WoW or running LiteMount after not having done so couple of years? Or did you somehow copy back your wow WTF folder from a really old copy?

If it's not that it looks like your WTF options for LiteMount got corrupted somehow. The only thing I can think of to suggest is to reset the options by deleting the LiteMount.lua file inside the WTF folder, or running

/run LiteMountDB = nil
/reload

Edit: fixed command
