Drupal 7 multisite setup white screen I have attempted to set up a Drupal 7 multi site set-up. I followed the instructions online and have one site (site1) that is setup like a regular single install Drupal site and a second site (site2) set up in the sites/sites2 directory. The sites use separate databases. 

The issue I am having is that while site1 displays and operates normally, site2 only displays a white screen. When I executed the install.php script for site2, everything seemed to go normally until I actually try to view the site. Any ideas as to what the issue could be? I am sure that settings.php file in both installations is set up correctly so I am a bit lost.

Thanks.
It is impossible to tell you exactly what is wrong with the information that is given.  I run several multi-sites using separate databases, and they work as advertised when I set them up following the standard instructions.

The White Screen of Death is usually caused by some error in the PHP.  To see the error message, you need to turn on PHP error reporting.  To do this, add the following to the settings.php, just below the initial &lt;?php:

error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);


This will usually show an error message that tells you where you've left out a semicolon or some other trivial PHP-error.
