Before we can declare the installation/upgrade a success and begin configuring your site, we need to test its basic functionality. The first way to test it is to click the "Go to your PostNuke site" and see if PostNuke comes up.
If you do not see a PostNuke page, something went wrong. The first thing to check is that no "index.html" file exists in your web directory. If there is such a file, rename it (or delete it) to prevent it from overriding the "index.php" file. Also, if you performed an upgrade to PostNuke, you may need to clear the cookies in your browser, and then restart your browser.
If you get a message that says something like: "Warning: Access denied for user: 'root@localhost' (Using password: YES) in newinstall.php on line 36 Unable to make database", then your database username and/or password is incorrectly defined.
You may wish to visit the PostNuke live support site located at http://www.postnuke.com/modules.php?op=modload&name=IRC_Chat&file=index for more assistance with this and other installation problems. Before accessing this page, it is necessary to register for a free account on http://www.postnuke.com.
If you see a PostNuke page, then the installation/upgrade was a success. You should now do the following:
Delete the entire install directory from the DocumentRoot (for example, /var/www/html/install). It is a security risk to leave it on the website.
Delete the install.php file from the DocumentRoot (for example, /var/www/html/install.php). It is a security risk to leave it on the website.
We can move forward into configuration, after a quick lesson in terminology.
