Disqus not appearing on your blog?
First you'll want to verify that you've entered the correct shortname within the Appearance settings. Note that a space or uppercase letters will conflict with Disqus functioning properly.
If your theme doesn't have a shortname setting or has been coded incorrectly, you'll want to using our Manual Installation Instructions.
If you're already using the manual installation instructions, please be sure to remove the "<" and ">" from either side of your shortname.
These customizations require an advanced understanding of HTML and may differ among Tumblr themes.
