No, it appears at random. Just now, I had a similar error screen saying “false is not defined”…it appeared when I tried to assign a tag to a word and it is reproducible (3x). Essentially, I cannot assign an established tag to a word (established meaning I have used that tag before): error2 hosted at ImgBB — ImgBB Edit: Seems unrelated to that particular word. I cannot tag anything right now…
