disclaimer: noob to PHP, MySQL, Plesk
For a client, I have installed the following in this order:
Tested the PHP install by creating an info.php. Everthing worked!
Installed Plesk 7.5.6.. Out of curiousity, ran the info.php again, but this time it came up with page cannot be found.
So, I looked in IIS and found that the default website is now pointing to another location other than the wwwroot. So, I copied the info.php to the folder, but still no dice.
