WordPress RSS feed suddenly stops working

[robcub]

My blog is at http://robcubbon.com/blog and the last two posts I've written haven't gone to the feedreader (I have the plugin installed).

I have tried cutting the posts down and have pinged it again at Feedburner's Troubleshootize. No luck.

I can see the last two blog posts:

Free 2010 Calendar in PDF and Adobe Illustrator file format
WordPress website designed with a little jQuery

I don't see any newer articles on your blog.

Thanks for getting back to me, c2uk. In WordPress, I'd cut down the feed in the administration area, Settings > Reading, "For each article in a feed, show - Summary" and I'd cut down the number in "Syndication feeds show the most recent" (it was 100). I did this before I posted this thread but the changes were slow to take effect.

I'd read somewhere that Feedburner can only handle feeds of under 512K. So my feed must have exceeded this size although I'd received no warning. Lesson learnt.
