The most common cause of feed problems is the content that you post. Many of our users utilize plugins as a method to automatically generate RSS Feeds. However, sometimes these feed generators can make formatting mistakes.
You can quickly check if your feed is valid at https://validator.w3.org/feed/.
So how do I keep those unwanted characters out of my feed/blog?
We recommend either using a plugin to compose your feed or that you compose your postings in a plain text editor, like Notepad on Windows, or TextEdit on the Mac. You can add HTML tags in your posts, as most blogging engines correctly format those tags for placement inside a feed. Copying from rich-text editors like Microsoft Word can cause invalid characters to appear in your feed.
Can dlvr.it tell me if my feed goes bad?
Sure. You can check your feed history under your feed settings to see any errors.
If you see specific errors, you may need to contact your feed hosting provider or content management systems specialists for assistance in resolving formatting issues.
An example of a properly formatted feed can be found at https://www.w3schools.com/xml/xml_rss.asp.
Your feed may also be reading as invalid because your feed hosting provider is blocking requests from dlvr.it
If this is the case, you'll need to make sure that dlvr.it is whitelisted in your incoming server settings. For more information about this, check out our support document that contains our server information.
