Just now, I imported some pages of zhwiki into my wiki. When I visited one of the pages, the page layout was disorganized, and some of these warning tell me: Lua错误 ...nsions/Scribunto/engines/LuaCommon/lualib/mwInit.lua的第23行：bad argument #1 to 'old_ipairs' (table expected, got nil). I think the Lua module I just imported is not compatible with my Lua parser.

the Lua is parsed just fine, but it has some logic error, or it requires the existence of a page/template/module on your wiki that doesn't exist.
