My site keeps reverting to the WordPress install page whenever I try to login or just visit the homepage.
I've been able to successfully login and do some work, but within a few minutes it goes back to the install page.
The website is http://uhclthesignal.com/wordpress and it's running the 3.5.1 version, which was installed the day it came out - haven't had any problems until now. Also, this isn't a new install, the site has been running since 2009.
I've check the database and all of the tables are ok, and the install.php file is in the wp-admin file. I even repaired the wp-options table, but it keeps reverting to the install page.
Any help with this would be greatly appreciated.
