I downloaded coffee cup ftp prog. I entered the ftp:// address I was given with the username and password but it says "are you sure you are connected to the internet"

I want to sort this out, I read about how annoying it is for you lot to continue to answer the same questions

How do I Change the Congratulations! Message?

If you want to change the Congratulations! You have successfully installed your Zen Cart™ E-Commerce Solution? Text with your own open the includes/languages/ENGLISH/index.php file and find the following code:

// This section deals with the "home" page at the top level with no options/products selected
/*Replace this text with the headline you would like for your shop.
For example: 'Welcome to My SHOP!'*/
define('HEADING_TITLE', 'Congratulations! You have successfully installed your
Zen Cart™ E-Commerce Solution.');
} elseif ($category_depth == 'nested') {
// This section deals with displaying a subcategory
/*Replace this line with the headline you would like for your shop. For
example: 'Welcome to My SHOP!'*/
define('HEADING_TITLE', 'Congratulations! You have successfully installed your
Zen Cart™ E-Commerce Solution.');
}

Replace the text starting Congratulations with your own text. Make sure that the single quote marks are not left out, save the file and upload to your server.

BUT I need to know how to upload files lol
