It looks like you just need to do step 4 - the second one (I'm assuming you're on shared hosting so it's unlikely that you will be able to openly edit your php.ini file or be allowed to upload a custom one to your root folder, so ignore the first step 4)
So open the 3 advised files (count.php, zerocounter.php, and del.php) and uncomment the include command at the top of the files.
Then you add the advised PHP counter include at the top of the web pages you want to track (right at the top - before any whitespace or Doctype), making sure the path to the counter is right. You may need to include the opening and closing PHP tags too;
Bear in mind that this is a PHP script so it runs on web pages ending .php
<?php include ("../counter/counter.php"); ?>
If yours aren't .php web pages, you can rename them and setup 301 redirects in .htaccess (if your web host permits .htaccess) to avoid destroying your SEO and indicate to search engines that the pages have moved http://301redirects.net/301-redirect...extensions.php
OR you can configure .html/.htm pages to parse PHP (if your server permits it and if you're allowed to edit your .htaccess file) http://stackoverflow.com/questions/4...n-as-php-files
If these method don't work, Google for alternatives or speak to your web host.
