Upgraded two blogs with no problems using the automatic upgrade button. The third blog I tried to upgrade ended up being a disaster.
Upgrade got stuck installing files
Ended up deleting both websites hosted in this account (they were two separate distinct websites using different URLs) – the upgrade deleted all directories and files, leaving me only cgi-bin and www folders. Thankfully, my database was spared.
The good news is that both websites were new and in progress, but this should never have happened. Whatever is wrong, WP needs to fix ASAP and pull the upgrade until it is. I would have been furious if this had happened with my other two sites that have been around for years and have tons of content.
As it is, I’m only angry, not furious.
