Hi Mike,
Sorry to hear of the problem you are having.
Is it working fine for you using any default WordPress theme like Twenty Thirteen?
Could you please share me the screenshots of your custom sidebar settings so that i can troubleshoot it?
For screenshots, you can simply provide a link to an image through Google Drive, Dropbox, screencast.com, http://imgur.com/ or other image service. 🙂
Kind Regards,
