I've NEVER had this problem before and have installed phpmyadmin many many times.
After installing the latest phpmyadmin on my plesk box with the latest php, i open my browser to point to the phpmyadmin folder. It says "Page cannot be displayed".
Now, the URL is right otherwise it would say "Page cannot be found". I don't understand why the phpmyadmin index page "cant be displayed".
NOTE: Plesk does have phpmyadmin in the user control panel which DOES work but I want to install my own much more updated version.
Also php is working properly as the rest of my site uses php and works just fine.
