This Space does not accept posts without external links or quora links

Why can't I post on my own space ("This Space does not accept posts without external links") when I tried one with links?

1. Go to Settings of your Space Search for the option

2. Under the “Which content types can be submitted to this Space?” content.

3. Click Advanced:

Disable External Links or quora links. It will help you post to your own Space now. It may also bring up a message that Quora Link is needed, disable all options not needed as your case may be.

Thankyou
