1. The above message (It doesn't look like you've installed WP yet. Try running install.php.) appears at the frontpage of my blog this morning. I checked my database, and all data are there and correct.
2. I have another blog installed in same server and running at another database and is working fine. So it couldnÂ´t be caused by a server upgrading error or something similar.
3. Both blogs run WP 1.5.2
4. I replaced all wp files (except wp-config.php) at the wp directories (main, wp-admin and wp-includes) and still getting the same error.
Just get no clue. Anybody help?
