问题
I had set up two Wordpress development sites, URL's were something like mysite.com/dev/blog1 and mysite.com/dev/blog2. blog2 would fetch posts from categories on blog1 using fetch_feed() e.g. fetch_feed(mysite.com/dev/blog1/category/fun/feed) and everything worked fine.
However, since moving the sites over to mysite.com/blog1 and mysite.com/blog2, the feed does not work. I get the following error:
A feed could not be found at mysite.com/blog1/category/fun/feed. A feed with an invalid mime type may fall victim to this error, or SimplePie was unable to auto-discover it.. Use force_feed() if you are certain this URL is a real feed." } } ["error_data"]=> array(0) { } }
When I go to the feed URL though, the feed does exist.
Any ideas?
回答1:
The fetch_feed() function is still trying to look at the dev. Highlighted below:
"A feed could not be found at mysite.com/dev/blog1/category/fun/feed. A feed with an invalid mime type may fall vic....."
You will need to remove the dev part from the url.

Had the same problem. I've tried different Wordpress RSS plugins and got the same result: "RSS Error: A feed could not be found at ..." (For almost all RSS feeds except for feeds from feedburner!)
I contacted our provider / web hosting service, they "unlocked" the domain of the rss feed within a minute and now it works perfectly!
If you're using a webhoster, maybe you need to contact their support for help.
