Since installing snapshot #1308 I’m getting the above error in Chrome and mobile Safari when viewing the basic UI sitemap. Anyone know if it’s a bug I should report, or some other problem?

See discussion here.

@Lolodomo has a workaround in the pipeline.

By any chance are you on an Android device?
