I agree that the 2.8 download should be removed from the WordPress site and especially the “upgrade available” from the admin. control panel.
I’m working on a new install. So far the main issue is Tags not being available when I create a Post. I get “No Tags Found!”, even though they’ve been created.
I see the mention of HyperDB as a possible culprit. How do I check for this? I’m hosting on GoDaddy, problem is consistent with latest versions of FireFox, Safari & Opera (Mac). Hopefully this can get worked out.
