Okay, so I'm upgrading my Drupal site and get the "White Screen of Death" when I run update.php. Of course I start sweating thinking "Oh my Gaw! My site can't be updated and I won't be able to add content and people won't see it and what's going on!"

Just for the record, last time I added content to my site was...
So you see why I'm in a panic.

Anyway, after lots of emails between myself and my web host's tech support I still had a white screen, but I knew that my site was running PHP5 and how to use phpinfo.php to check that, although in my control panel PHP4 was still showing.

This is a hilarious video from Zoobie.tv on the repercussions of misusing (or should I say misclicking) Google Ads on your site.

The funny thing is my Adsense account was disabled when I did nothing, unlike Zoobie who clicked on his own ads.
I was told there were "invalid clicks and/or impressions" generated on my ads. What? Like I have time to sit there and click my own ads when I'm in the throws of putting my site together, not to mention, I HAVE a life.
