Is there any progress on this or can I just assume this script is dead for now?
I never actually made any progress with it, and it mysteriously started working for me for a period so I forgot about trying to fix it. Maybe one of the more regular maintainers has some more info though.
the script worked perfectly for me on a computer at home, but ever since I got a new laptop Iāve tried many times to get it running and I just canāt 
Iām getting the empty circle too. Is there anything that can be done?
This script is no longer supported. Youāll want these 2 scripts instead:
Iāve been using the unsupported script until the new wanikani dashboard was implemented. Now that it is gone, I came back here to discover the Self-Study Quiz has new options for quizzing leeches. Itās better than the original Leech Training script because it has customising options.
@rfindley, I canāt thank you enough for your efforts. Itās amazing work you do for us.
The access to this script is gone now, could this be updated?
Iāll take a look. Hopefully have some time this weekend.
Give that a whirl, version 2.0 has been uploaded.
Itās very late in this time zone, Iāll try tomorrow 
Thereās a bug; itāll only allow you to do one session and then it breaks. 2.1.0 coming later today, hopefullyā¦
2.1.0 is released. It was also automatically close the quiz after a session.
Thanks @rosshendry. I thought this script was no longer supported because of the topic heading. Maybe this thread should be locked and you can start a new thread.
I confirm that the leech training script is working on Safari browser.
That seems sensible, no point in continuing to post in an āunsupportedā thread.
New Leech Trainer! [Userscript] Leech training
It works perfectly! Thank you so much! Sorry for my late response. 
I noticed that the api key in my local storage has the title āapiv2_keyā rather than āapiKey_v2ā which is referenced in this script in the get_api_key() function. It was causing an error in my console so I tracked it down to this script.
Iāve been using this script a lot recently and found it very helpfulā¦but something seems offā¦or Iām making a mistake somehowā¦
when I get to Heart Shaped (stupid rendaku) always seem to forget after 4 months when it comes around to burnā¦but anyway ā¦ it wonāt accept it and the entry field just bouncesā¦
This is how I normally input to WK
Then if I deliberately type a wrong answer it does show the error:
But if you go back to the correct it still wonāt proceed and bounces so I thought well letās try katakana and hiragana and still same thingā¦
So itās either somethings broken with this one particular item, the script or the idiot behind the keyboard ā¦any one know whatās going on? how to fix?
Closing thread as itās unsupported.
