This problem has bugged me for a while.
I would set it to send summary to RSS readers. Within a couple of hours, it would revert back to full text.
Anyone else facing this bug? Is there any solution? Any plugin conflict?
I have following plugins running on the blog:
All in One SEO Pack
Dagon Design Sitemap Generator
Daily Top 10 Posts
Dean's Permalinks Migration
Google XML Sitemaps
Periods in Title
Post Editor Buttons
W3 Total Cache
