Lunar Sphere

[Schaufel]

I know Lunar Sphere was abandoned several years ago, but it still works just fine. I have no idea how to read the addon code language, so I was wondering if someone could tell me exactly what to edit in the LUA with the live patch in order to make this error message go away. Again, the functions of Lunar Sphere still work just fine; this error popping up upon login is just annoying.

Thanks!
