Installing Drupal

I'm working on my first site, I manually installed Drupal 7, then I decided I wanted to try something else, so I went about deleting all the files/folders and the database.

However, the Drupal favicon is still showing in the browser window, and the server still says that about 12MB is being used somewhere. The server was basically empty before the install. It should only be showing around 2-3MB. I checked where the memory was being used and it's listed as being in "Other".

I could really use some help here. I'm stumped.

Apache 2.2.17 (with AllowOverride All)
PHP 5.3.4 (with php-pdo installed)
MYSQL 5.1.54 (with InnoDB)

I am having a problem installing Drupal 7 on FreeBSD 8.1. The installation proceeds well until I fill out the Configure Site page, then press 'Save and Continue' a WSOD page appears. Up until this point the database has been created with 73 tables but there is nothing in the users table ie., no admin user has been created. I have looked in the watchdog table and there are no useful clues. I have set my apache logs to debug and again no useful information, other than "File does not exist:/*/*/drupal-7.0/favicon.ico" which suggests to me the .htacess file is being read OK. I have enabled display_errors as TRUE in index.php with no error output.

I have been mostly doing the install using Firefox and WSOD is complete white. When I tried with Chrome I got this error msg "The web page at http://****.co.uk/install.php?profile=standard&locale=en might be temporarily down or it may have moved permanently to a new web address."

If I try to go to the site root with index.php it shows the D7 login page but when I try to login as admin it says no user name (obvious after I found no users in the table).

An AJAX HTTP error occurred. HTTP Result Code: 500 Debugging information follows. Path:

Hey forum. I'm running my current Drupal 6.19 site on Debian and the standard Drupal core. Setting up a new VPS and want to use Mercury. Need to figure out whether to stick with Debian or move to Ubuntu 9.10 or 9.04. Any recommendations would be awesome. THANKS.

Fresh install of D7. Since it's a parse error, I'm not sure what to do.

The general structure of the area that's throwing the error is as follows:

function {
  if {
  }
  elseif {
  }
  else {
    try { // this is the line throwing the error
      if {
        if {
        }
      }
  }
}

It seems odd.. Coda is telling me the brackets are correctly laid out.. and I don't see any particular syntax error in the code.

I am trying to do a clean install of D7 on an ArchLinux machine. This machine has all the latest updates installed.

PHP 5.3.5 is installed and working -- I can view the test.php page with no problems from a browser window.

When I try to run the D7 install.php script I get a blank screen. Checking the apache log, I find:

"PHP Fatal error: Call to undefined function json_encode() in /srv/http/drupal/includes/common.inc on line 4797."

According to the test.php output, json support is enabled in php and I can find the json.so library in the php installation.
