hoovard said... I have a copy of it. Here is a link to a zip of a folder containing the script and the jquery that goes with itThanks! I managed to fix this problem. I think it was a conflict between 2 jQuerry versions, one from wanikani one from the script.

However, since yesterday the script has stopped working, the reviews hang on the loading screen.
So a fix is to add this:
// @grant noneTo ==UserScript== section and add this:
// @require https://gist.githubusercontent.com/arantius/3123124/raw/grant-none-shim.js
this.$ = this.jQuery = jQuery.noConflict(true);after ==UserScript== section.
This also fixes Wanikani Show Level script which I had problems with same as yours.
I don't know how good a fix this is but it at least works!
