  As part of my troubleshooting, I checked the Developer Console and saw a couple errors originating from Craft's javascript files that were stored in the /cpresources directory.
  
  As an attempted fix, I deleted the /cpresources directory which lives in the web root. This directory automatically rebuilds itself if it's not there. After the directory rebuilt itself, the error went away and I was able to log into the control panel again.
