That's a classic error caused by "Module:No globals". To put it in layman's terms, that module tries to make sure there aren't any modules using "stuff" that isn't  defined within a specific area.

The easiest way to kill that issue is to remove "require("Module:No globals")" from all wikipedia modules. It shouldn't really affect how they work. The problem is that they often have other issues that need to be solved before they work in Wikia.

To deal with them you'll really need a good understanding of how it all fits together (and LUA), as cqm notes. Another way to fix it is by reverting all templates to their last working revision.
