We updated W3 Total Cache earlier this week to Version 0.9.2.7 and since have been having issues with our RSS feed updating - it seems to be delayed by about 8 hours from when our blog post goes live.
I've tried pinging the site through Feedburner's ping service, but I get this error:
"Your Ping resulted in an Error "We were unable to process your ping. You must ping with a URL that exactly matches the channel link (RSS) or alternate link (Atom) in your top level feed element pointing back to your website (e.g http://myblog.blogspot.com/), or use your feed URL (e.g. http://feeds.feedburner.com/myuri)."
Their resync feature has also not helped.
After reading some threads here I disabled "Cache feeds" under the Page Cache menu but it still has not helped.
Any thoughts would be GREATLY appreciated.
