I have a site that is running Drupal 7.17 with a very standard set of modules and CiviCRM.  When I upgrade the site all pages are redirected to install.php.  

I have checked and my sites folder is configured correctly and I have tried looking at the .htaccess files and anything else I could think of.  I am at somewhat of a loss here.  

Any help is greatly appreciated.  

Thanks,
Steve
