I am unable to access any of the lab resources. When I click on the links, it directs me to a blank page.

Troubleshooting steps:  

1. This issue is typically caused by plug-ins like AdBlock. To resolve it, please ensure that you do not have any such plug-ins enabled. You can find instructions on how to temporarily disable the AdBlock plug-in here.
2. A lot of lab resources are PDF files, make sure your browser has a PDF view functionality enabled. Learn how to use the Chrome PDF viewer in here.
