I have an RSS feed generated from my blog posts. This feed goes to many places, including my LinkedIn profile and web site. All of a sudden, it stopped working - now in all the places that were fed, the message "The feed URL http://mysiteaddress/?feed=rss2 is inaccessible." displays.
If I click on the RSS icon on the blog, the following message displays: "ERROR: rss2 is not a valid feed template".
Any ideas why it happened?
Many thanks in advance!
