After upgrading from 3.0.5 to 3.1 it seems that my feeds do not longer work. I have two sub sites with new articles since then - they have been published on the 25th and today on the 28th the feeds still not listing the new articles.
I ran the domain mapping plugin and use feedburner for my feeds. The original feed is forwarded to feedburner by a plugin. Disabling the plugin seems not to work either and also the native feed is not listing the latest articles.
What I can I do or try to fix it?
