I get this error when going to the url to install:
Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /directory/directory/directory/directory/install.php on line 518.

Here is the code from lines 508 to 536:

function isRunningApache($testDetails) {
      $this->testing($testDetails);
      if(function_exists('apache_get_modules') || stristr($_SERVER['SERVER_SIGNATURE'], 'Apache'))
         return true;
      
      $this->warning($testDetails);
      return false;
   }

line 518->protected $baseDir;
   function getBaseDir() {
      // Cache the value so that when the installer mucks with SCRIPT_FILENAME half way through, this method
      // still returns the correct value.
      if(!$this->baseDir) $this->baseDir = realpath(dirname($_SERVER['SCRIPT_FILENAME'])) . '/';
      return $this->baseDir;
   }
   
   function testing($testDetails) {
      if(!$testDetails) return;
      
      $section = $testDetails[0];
      $test = $testDetails[1];
      
      $message = "OK";
      if(isset($testDetails[3])) $message .= " ($testDetails[3])";

      $this->tests[$section][$test] = array("good", $message);
   }

This is running on a 1and1 Linux shared server, if that helps any. The url to the install is:
www.fairmidway.org/install.php

Thanks.

Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION is the usual error message when you have PHP4 running and not PHP5 - how you can check is by creating a somefilename.php with the content

Upload that to your server and see what version of PHP you are running

sorry should be phpinfo() Note no _
