I woke this morning to find that my site is getting the "It doesn't look like you've installed WP yet. Try running install.php." error, seemingly randomly, when clicking on links:
I haven't touched the configuration at all, and this suddenly started happening. The site itself seems fine, when reloading links, but the error keeps popping up. Any ideas what would cause this?
Edit: I discovered the reason: My host just upgraded to PHP 4.4.0. How can I get rid of this error?
