It’s still happening to me
If anyone is still experiencing this issue, could you write to us at hello@wanikani.com so we can properly document it?
We’ll want to know what browser and version you’re running, as well if you’re using any scripts. If you are using scripts, we’ll want to see if you still experience the issue with all scripts turned off.
If you’re not running any scripts and still having the issue, we’ll want to see a screenshot with the web inspector open set to the console tab. If that doesn’t make sense, we can provide instructions over email!
same, will send an email
I disabled the “Wanikani: Lesson and review deep click” userscript and it stop appearing for me
(Also Anki mode and Workload graph but I think that one is the culprit)
Hey @marlanbar! Thanks for bringing this up. Is anyone else using the “Wanikani: Lesson and review deep click” user script and experiencing this issue? If so, could you try turning it off as well to see if it resolves?

It appeared again
I don’t use any userscripts, even Tampermonkey or whatever one need to have for it, but I regularly see some “shadow” 1-5 reviews right after reviewing. Refreshing the page makes it disappear. Clicking the “Review” button results in “You have no items to review right now.”
And this is how it looks like
click
The main page have some refresh delay indeed.
Just after a review session I got this:
30/30 kanji, huh, shouldn’t it be level up then?
Then I refresh the page

I don’t have any scripts installed.
My best guess that this became a thing after removing stats page and redirecting directly to the main page. Because previously one had to see the stats before manually navigating to the main page, and probably this is why no one never saw its inconsistent state it have for a few seconds right after a review session.
Was this bug fixed? Since a bit ago I get a markedly different behaviour with my last review (can’t describe, how it’s different though) and even with double check I never get the bug.
I actually just got the bug today after finishing some lessons. It logged the newly learned kanji though, so I’m a bit confused. I appreciate the message though!
Same here. I’ve just done some reviews and I got the same message. Honestly, I got paranoid that Wanikani might be tracking my location or something… Until I went on here and found this thread.
I’m using Google Chrome with a number of scripts enabled through Tamper Monkey.
Bug? I figured it was just something that pops up if you click around the site enough.
I saw it earlier (FF, no scripts) after taking a break between my big batch of reviews (213 items)
I started getting that message pretty regularly (but not always) after reviews last night. Multiple computers, multiple browsers (Firefox, Chrome, Edge). No plugins/scripts.
Could you provide the steps to reproduce the error you are seeing? I have just tried to recreate the issue but can’t.
e.g.
- reload the dashboard and see no error messages
- click start reviews button on the dashboard
- … please explain steps further. i.e. do you do all reviews on are you using the wrap-up button?
on edge i get it every single time after i finish a batch of new lessons
Just did 25 lessons, each time went > Advanced > choose 5 words > finish and go back to dashboard. Got the message each time i finished a batch
Edit: not using any wrap up button, just organically finishing the lessons
Thanks, I just followed those steps but still no error. Which scripts are you using on WaniKani?
these are all the ones i have installed, through tampermonkey
(had all of them for a while, no new ones at least for the last 3-4 weeks i think?)
Thanks for that. My guess is one of those scripts is doing something unexpected. Unfortunately where scripts are concerned I can’t be of further assistance. Scripts should come with the warning that their use may break things from time to time, and these breakages are the responsibility of the people that write them or install them.
Most scripts should have this at the top of their page:
This is a third-party script/app and is not created by the WaniKani team. By using this, you understand that it can stop working at any time or be discontinued indefinitely.
Yeah for sure, i dont mind it much personally. Just wondering if its the scripts fault, since @TezuSubs for example said they didnt have scripts
also just for fun i tried to play around with activating and deactivating some scripts and see if it changes anything but the conclusion is kinda just “i still dont get it but it got me to do more lessons ”
For ppl interested or struggling with it:
-
I tried activating/deactivating only one of my active scripts at a time, with deactivating double check OR self study quiz i did get 3 tries without the messages in a row (didnt try more times bc after all i did have to do lessons for it
) but that also doesnt make that much sense, bc if e.g. double check caused it then why did i not get the message when i had it on and deactived self study quiz …
-
when i deactived pitch info i tried like 6 times and i got it 4 times and didnt get it 2 times (same settings tho) → so i almost think it has nothing to do with the scripts? and has some other random factor and it was just “lucky” when i didnt get it 3 times a row in the prior step and got unlucky when i got it 5 times in a row in my usual lessons
-
If the lesson is ending on a reading or a meaning didnt seem to have an effect
-
also tried if “clicking next super fast” caused the error but there also didnt seem to be no connection
my internet isnt the greatest in general so it might be something about some response time thing with the server, no idea about that stuff tho
I’ve been having the same “Explorer” error message bug the past couple days, whether it’s after lessons or reviews, and I have no scripts enabled. It happens multiple times a day after returning to my dashboard but there’s nothing that seems to particularly trigger it.
