I try to install it on my account and get the error (as shown in the picture). I went to the "application" folder, renamed "database_sample.php" to "database.php", edited the information there and then imported the "mysql.sql" file to the database but still could not!

I went to the file "Connection.php" according to the notice and found 2 entries I do not understand what that is!

Can someone guide me how to install it? Or I hope a new install is great!
