I just installed wordpress on my server, and spent 6-7 importing my old posts, fixing up the template, etc. I was refreshing as I was going along and everything was going fine.
Suddenly, one of my refreshes gave me a 404 error. I thought it was weird, so I clicked on my categories and it gave me a 404 error. Everything else was giving me a 404 error except my root page. After refreshing a few times, my root page disappeared as well and it gave me a:
'It doesn't look like you've installed WP yet. Try running install.php.' error.
It was like my whole WP blog just virtually disappeared by itself.
I contacted my server admin about the matter, and they informed me that mySQL database is running fine, and said I should contact the WP support.
Really hope someone here can help me as I have no idea what's going on, and I don't want to reinstall and reedit to have it disappear on me again.
Thanks in advance.
