Hello, X-Carters!
This post is for everyone, who has
experienced troubles with the language variables missing.
We have fixed this issue. Please download the new version (1.0.4) of module from the HelpDesk File Area and replace the following files in your X-Cart with the updated ones:
modules/Xcart_Mobile/config.php
modules/Xcart_Mobile/customer.php
modules/Xcart_Mobile/admin.php
Or you can just unzip the module package to your XC root and allow the files replacement; the SQL-patch is not needed.
