I tried to follow the instructions but must be missing something.
I copied all the PS files to C:\XAMPP\htdocs\myfolder
I Opened IE File\Open\Browse
I browsed to the correct folder
Under File Types it defaults to HTML files and none show.
I selected All Files highlighted index.php and clicked open.
The file opened as a text document.
XAMPP control panel shows Apache and MySQL both running.
Can you see what I am doing wrong please?
