I'm running a blog with WP 2.6.1. I created a post yesterday that linked several sites with Trackback URIs, and listed them in the "trackback" box as usual. However, none of them were sent, and the "edit post" page (a day later" continues to show no pings.
I've sent trackbacks successfully in the past, and the sites in question clearly display incoming trackbacks from other sources, so I was perplexed. Diving into my CPanel and opening up phpMyAdmin, I discovered that in the "posts" table in the database, they were all still listed in the "to ping" column, rather than "pinged."
Anyone have any idea what's going on, or what to do about it?
