I’m having this issue too.
A feed could not be found at https://groups.google.com/forum/feed/sonbuyruk-kilisesi/msgs/rss.xml?num=7. 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.
But when I copy and paste the above Feed URI into a browser the XML shows up.
What can we do?
