The database upgrade screen never shows any more details. You’re seeing what you’re meant to see.
The next screen is not meant to white-screen. Can you look at your web server’s error logs (your web host should be able to help you access if needed) and see what the error messages are? They’ll probably begin “PHP Error”.
Hi, I have the same exact problem!
This is what I get in my PHP log file:
`[10-Jul-2012 19:39:48] PHP Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 77824 bytes) in /var/www/wordpress/wp-admin/includes/upgrade.php on line 1559

Please help me! How can I fix this issue?
Sorry to answer my own question, but I found the solution online. I was able to solve the problem by adding the following line to my wp_config.php file:
`ini_set(“memory_limit”,”64M”);`
In this case I doubled the PHP memory limit.
