just because some got obvious way to share something
before to use any php just check EVERY file ...
I don't where the bad could be if you CHeck the files...
regards
EDIT :
Missing on bank teller or desactivate it
include "../PowerAuth.php";// Database configuration parameters
Out of that the files look Clean...
After there is maybe other kinda to write ! but that it's nice
So thank you for contribution on Shaiya and then Update your Post to repair the missing files ...
