Please provide any additional information below.

 UnitAura was deprecated in 10.2.5 (https://warcraft.wiki.gg/wiki/Patch_10.2.5/API_changes)

Ummm, UnitAura was not removed, It will be removed on next expasion at the end of the year.

Try Grid2 with all other addons disabled.

Update:

It seems you are using the RealUI compilation. Probably this interface replacement compilation is not loading the required blizzard code.

Try updating RealUI, because you are not using the latest version.
