Yesterday, I could click on "upload" and upload files just fine. Today, I can't do it. I get no error message--in fact, WP says the file has been uploaded successfully. The only reason I know it hasn't right off the bat is because WP says the file size is "0 KB".
Any idea why this would happen? I've checked that the paths are correct and they are. I've CHMODed my uploads dir to 777. As I said, I uploaded something fine 24 hours ago, but today nothing will upload. I'm running wp1.2.2
