I have the latest version of Joomla 3, and just installed the Disqus plugin. My only problem is that the Color scheme, doesn't change when I set it with Disqus. I have a dark background, but when I set it to dark background it makes no difference. It is still too light to see.

Also my Joomla component doesn't work, but the plugins work file.

I am unable to verify my installation from the disqus website as well. Hope you can help!

Could you provide a link to your site to check it out?
Thank you.

I found the style sheet under plugins/content and change the background manually, so it works now. thanks

You are welcome and glad you sorted it out.
