My debugging information, just for reference:
Error: Module:Navbar:25: bad argument #1 to
'sub' (string expected, got nil)
if mw.ustring.sub(pageName, 1, 1) ==
':' then
pageName is nil
function _navbar( args )
if not args[1] then
return error('No name provided')
end
args[1] is not nil
local good, title, talk_title; good, title,
talk_title = pcall( getTitle, args[1] );
Likely pcall-related issue (ignored args[1])
