Using IE11, open URL: https://wpcalypso.wordpress.com/devdocs\r\n2. Click the \"UI Components\" link\r\n\r\n#### What I expected\r\nTo see the design components\r\n\r\n#### What happened instead\r\nA blank screen is displayed, with the following console error:\r\n`Unable to get property 'replace' of undefined or null reference`\r\n\r\nThe last time I can verify that it worked was two days ago, September 27th, the last time the cross-browser visual diff tests were run.  My hunch is that there's a single component that's breaking it, but #7866 also went in two days ago with sweeping changes to the devdocs structures.  It's likely a combination - a component or two that's breaking things, but not necessarily because they changed in the last two days, since the system around them changed.\r\n\r\ncc: @retrofox \r\n\r\n#### Browser / OS version\r\nWindows 7 IE11\r\n\r\n#### Screenshot / Video\r\n<img width=\"969\" alt=\"screen shot 2016-09-29 at 12 22 18 pm\" src=\"https://cloud.githubusercontent.com/assets/7233112/18962577/6f8fac1a-863f-11e6-97c6-684066eb3af8.png\">\r\n\r\n\r\n#### Context / Source\r\n#automated-testing"}}
