Dude, your screenshot is of the Dashboard plugin. It's a relatively-new plugin by an author who now has a total of one plugin under his belt.
If you don't say otherwise, we assume that you've installed via the OctoPi image. So I'm guessing that you're running some sort of Debian rather than Raspbian and that you didn't image from the OctoPi image. The printer safety check bundled plugin is a safety feature, by the way (it's disabled on yours).

Like I said before, try it in Safe Mode and share that version of the log.
