Frickin’ 3.0 Has killed me! Thanks to BITS’s advice above, I am rolling back ALL of my sites to WP 2.9.2, and so far so good. Will try Dizynit’s advice on upgrading, but only one at time and on a site I don’t care about FIRST! Truly amazed at how little there is on the web re: this problem, and the incurable ERROR CODE 324!
