Recent update to WaniKani has broken many scripts. Here are few things to try:
- update all scripts
- if that didn’t work, look for the forum threads related to broken scripts, you may find how to fix them
- some scripts may be working but you need to go to their settings and choose new position since the website structure has changed too and the scripts don’t know where to insert their stuff
- Try this script I implemented that may help with some scripts that were not updated: [Userscript] Script loading fix
