I assume you're talking about Street View itself not showing up and not the blue lines indicating where Street View can be found? I can't say I'm experiencing the same issue, I'm afraid. I did see a couple of people saying something similar earlier today.
Either way, I'm pretty certain that is an issue that is not related to this userscript, so I can't help with that.
