I’ve been trying to figure out why the edit comments feature didn’t work. It may be fixed (I hope so).
I’m using a plugin called WP Ajax Edit Comments, which worked like a charm for a long time but (apparently through a dispute with WordPerfect about upgrades) got disabled. The dispute has been resolved, and I hope that means it may be working.
The other day when the blog blew up, it happened about the same time as I updated some plugins while trying to get to the bottom of comment editing, and that caused me to conclude my changes had been what had blown up the blog (it turns out this was just a timing coincidence; to tell what actually occurred involve a long boring story of technical support). It did improve my backup habits, which is a good thing. But in any event, let me know if the comment editing works.
