Thunderbird avenging the pigeons?
It may be the revenge of the birds, but there seems to be an issue with the latest version of Thunderbird in terms of RSS feed: here is an email from Umberto I got very recently
(…) I have just discovered I missed the latest RSS feeds (the last one downloaded on my Thunderbird for Windows is http://xianblog.wordpress.com/2011/11/08/inherent-difficulties-of-non-bayesian-likelihood-based-inference/) i.e. those published after 8th November.
This happened simultaneously on my 2 computers and only for the POSTS feed of your blog. RSS feeds from other blogs give no problem. Also I have no problem with the Comments feed. This is might be related to the latest Thunderbird version (v. 8.0) which has been been released on 8th November = date of the latest downloaded feed (!).
I have deleted the feed to your posts and tried to install them again but now I get a “http://xianblog.wordpress.com/feed is not a valid feed”. Reinstalling Thunderbird didn’t solve the issue nor even going back to the latest working Thunderbird installation. So I am writing you to let you know about this issue, not to solve my own specific problem but just in case the issue is not due to Thunderbird but to some settings you might have recently modified in your blog.
I have no idea about the problem nor the solution. There was something similar discussed on wordpress five years ago, but unlikely to apply. I will certainly contact wordpress and let interested readers know if they come up with a solution (or at least a reason).
