Installing Drupal

I am trying to install WAMP from wampservice.com
The download and installation go smoothly, but when I try opening http://localhost/, the screen appears totally blank.

Why do you think is that?

Thank you in advance!
I am an absolute newbie to Drupal and using http://localhost/.

Resolved my own issue

I recently reinstalled my OS (FreeBSD 8.1), along with Apache+modperl-1.3, MySql-client-5.0, and Mysql-server-5.0.

Presently, I can not get MySql to connect to my existing Drupal installations, with the error appearing on my home page, advising that the site is under maintenance: "The MySql error was 'Socket operation on non-socket'".

I checked /tmp and mysql.sock (a common problem) is there. I am not running SSL. I am therefore not sure what the "socket" issue might be. After googling, this does not appear to be a widespread problem, leaving me at a loss.

Hi,

Tried to implement XCache on our Apache 2.0 server. The version used is XCache 1.2.2 with PHP 5.2.17. Instant white screen, as soon as i configure the Cache Router settings. If i am commenting line number 36 in xcache.php file it working but it's taking more time to page load.
function get($key) {
$cache = parent::get($this->key($key));
if (isset($cache)) {
return $cache;
}

// Get item from cache
$cache = xcache_get($this->key($key));

I'm installing Drupal 7 on the servers at NearlyFreeSpeech.net. (First time with 7, I started with 5.x years ago, used 6.x for a while, it's been about a couple years since then)

After uploading the files, changing the appropriate permissions, creating the MySQL database, I go to install.php. I go through the "choose profile" and "choose language" pages fine, then I hit this error:

Fatal error: Call to undefined function class_implements() in /f5/[mysitenamehere]/public/includes/file.inc on line 141
