You must go to your webhost space (ftp server) and search for that files and then chmod them.
( chmod = with to choice the files and click on the right on properties en then 777 for the permissions)
This error you get is because the file constants_arcade.php dindt find in the directory includes/
The soulusion copy the file constants_arcade.php to the includes directory.
