Title Unknown RSS Feed

Have you added this as a site title in Settings/General?

Yes,
It’s listed as
https://www.nusparkmarketing.com

Site address and wordpress address are the same..

That’s the site url. What is entered in the Site Title field?

Simply

NuSpark Marketing

Actually, I’ve just looked at your feed and it’s fine. The site title is there.

Favor then,
Please subscribe to my blog on my blog page and see what you get as a Feed title? Mine says unknown tite, and that’s what my partner sees.
Not sure what the problem is.

Thanks.

It could be your feed reader. Right now all of your feeds appear to be redirected to Feedburner, so it’s difficult to validate the source feeds.
