FeedBurner plugin for WordPress had an upgrade some time back to version 2.1.
Basically the plugin detects all access to your feed (e.g. https://venukb.com/blog/feed/ or https://venukb.com/blog/wp-rss2.php, etc.), and redirects them to your FeedBurner feed so you can track every possible subscriber.
Unlike the older version, the new version of the plugin doesn’t use the .htaccess file. Also the old Feedburner URL doesn’t work with the new 2.1 version of the plugin.
So requesting all subscribers to update the RSS feed of this blog.
1. If you are subscribed via https://www.venukb.com/blog/feed, there is no change, and the plugin takes care of automaticaly redirecting the feeds to feedburner.
2. If you are subscribed via the FeedBurner URL i.e. http://feeds.feedburner.com/venukb/zrq , then the feeds will not work properly.
