Looks like I have the same problem in the qgrid demo notebook.

Thank you for reporting the issue @TimShawver. Yahoo data has been giving problems for quite some time. I recently fixed the example NBs (after release v0.2.1) and now they are broken again. I won't chase Yahoo anymore, not until their API stabilize. Maybe it's time to build examples on other data source. Would you like to provide a PR?

Yea sounds like we'll need to use another data source. I won't have time to work on this unfortunately, just wanted to make sure you were aware of the issue. Last time I checked the Yahoo API was working at least intermittently, so it was news to me that it had stopped working entirely.

Indeed I wasn't aware of the new API breakage, thanks for reporting this.
