An FTP client is a software program that lets you access the files on a web server via FTP (File Transfer Protocol).
Newer versions of Windows and Mac OS have FTP clients built in. There are also many free third-party FTP clients such as FileZilla. I don’t have a recommendation about which one to use but any of them should work. Once you have an FTP client, you will need to give it your web server’s FTP address and username and password. If you don’t have that info, contact your web host.
Once you have access to the server, be careful not to delete any of the files on your server by accident. Search the folders on the server for one called wp-content and then follow this path: wp-content/themes/[your-theme]/woocommerce/cart/
Inside the cart folder, you should see a file called cart.php. Using the FTP client, copy cart.php onto your computer and make a backup copy of it. Open cart.php with a text editor and delete the line that looks like this:
<?php woocommerce_cart_totals(); ?>
Save the new version of cart.php and, using the FTP client, upload it back to the cart folder. You will probably be asked if you want to replace the existing cart.php file. Choose yes and then check your website to see if the problem is gone.
