I was testing out running LAMP on Ubuntu 10.04. I tried installing WordPress to see if I had the databases up and functioning. However, I kept getting a blank screen on install. It seemed that no matter what I did, it wouldn’t work. I tried connecting to the database using the same information on another page and it worked. I didn’t get the problem.
Then, I found that I needed to put this into the terminal:
chown -R www-data /var/www/wordpress
That was it. Did that, and it worked! 
Crazy, huh?
