Weird pop up on WK all of a sudden

[akihikoo]

I am using Wanikani on my MacBook and I use Safari. I have installed the heat map script ([Userscript] Wanikani Heatmap). I have been using WK for over 45 days now and I haven’t seen this (screenshot attached) error before.

Is this related to my browser cache or something that WK usually alerts people?

Thanks,

It seems to be an issue with Safari according to knowledgeable folks in this thread: Using Storage

What version of Safari do you have? I have 12.1.1 and I’ve never seen this popup.

Yeah, looks like that. But I am not sure what the issue is. Thank you for linking that post. I’ll keep a watch on that.
