Thread:Extension talk:Scribunto/Template import and Script error - "Lua error: Internal error: The interpreter exited with status 1."/reply (5)

I suspect the problem with the ExtensionDistributor link is that people are downloading the 1.21 version rather than master. Once 1.22 is released (whenever that is) this should be less of an issue, since it's less likely that major changes will be made in 1.23 as they were while the extension was still being actively debugged and developed shortly after the MW 1.21 branch.
