That line is just a MW setting that turns on debug for MW, so if that's it there's a bug in Wikia.

It mostly controls which .js gets minified so you can debug through functions on the browser, so they have something broken down in the bowels of the file chooser in MW if that's affecting the witcher slider, which is pure JQuery. Maybe its picking one JQ or Wikia version that's minified and one that's not and the non-minfied version has bugs or is incompatible.

Ill flip it back to on for test and see just so we know, but regardless Ill make sure to not push a public change that has it on. I'll make sure the public commit is done with it off for now also.

It should have been harmless, as its how you are able to debug code previously for anything that's not include article and been used many many times across all the wikis. And for years before the new test facility, you had no choice but to have it on live for everyone, so has had a long history of live use and shouldn't have broken anything. :( That's too bad is buggy atm.
