I am using WordPress version 2.6.5. On one (and only one) of my blogs, I set the "Settings > Reading > Article Feed" setting to "Summary", and after a few minutes or hours it automatically reverts back to "Full Text."
This has happened ever since I upgraded to version 2.6.*. I've tried turning off plugins, but it keeps happening. I've also reset my passwords and checked all my permissions. Sometimes it will go 12 hours before it changes back, and other times it will revert to Full Text every hour. Very odd!
Is WordPress getting hacked? Is there a bug? What could be changing this setting continually without my permission?
