First off, a bit of background: I had to do an erase and install about 2-3 weeks ago, so this is a fresh, up-to-date installation of Snow Leopard we're dealing with.
That said, I decided recently to branch out from simply programming PHP in a text editor and explore some of the other technologies I keep hearing about, and picked up Drupal, Joomla, and the Zend Framework from their respective official sites. Latest complete, stable builds for all 3.
Drupal and Joomla downloaded without a problem, but when I put them in my /~username/Sites folder, XAMPP pretends they're not there, even if I restart Apache or the laptop itself. Zend's archive won't open at all.
Is Safari corrupting the downloads, or are there other issues in play that can be investigated?
