Our Support team is ready to present a new tutorial that will show you how to change navigation bar pages titles (breadcrumbs) in OsCommerce.
On your site, hover over the title (link) to find out the name of the file you need to edit:
Navigate to includes/languages/english folder (or to another folder with needed language) on your FTP and open the file with the same name for editing.
Edit the following line:
define('NAVBAR_TITLE', 'Contact us');
When you are done, click Save.
Check your site to see the changes.
Feel free to check the detailed video tutorial below:
