My site runs fine and loads fast from the front end. But on the admin side, when I try to add a new post or edit an existing one, the publish hangs and appears to not work. Sometimes, if I look at the "edit posts" page, I see my post sitting there as a draft. I can then publish from there and it works.
I'm running Firefox 3.6.3 (and WP 2.9.2). I'm pretty sure I've got PHP5 enabled on the web host (LunarPages). I've cleared cache, cleared cookies, and restarted. Same problem. Tried it in IE8. Same problem. I've seen some other forum posts where network speed issues were raised, but I don't think this has anything to do with connectivity, since just about every other type of network traffic runs fine.
I've got another client's site on a GoDaddy hosting plan, also running WP 2.9.2, and I sometimes see the same problem.
Any clue what's going on? I don't know if the problem is in WP, MySQL, my web hosting plan, my browser, my connection, or a million other things it could be. I'm willing to spend some time trouble-shooting, but I don't even know what to look at. I'm quite tech-savvy (I sometimes accidentally say things like 'ping', 'traceroute', and 'w3c validator' in normal conversations) so I'm not afraid to look under the hood.
