Okay, I updated to version 2.62.0, and after a lot of searching, I found where to whitelist sites. Unfortunately, the option is broken.
Under the "Customize" tab, It gives a link for adding whitelisted sites. When I click the link, a text field drops down, but text entry is disabled in it. So, I can't add anything to it.
In the end, I just temporarily switched off AdBlock so that I could get access to the site I wanted to see. Then turned it back on after I was done.
