I may support this feature in future but definitely not in the near future.
Sorry but currently this plugin does not support that feature.
Sorry. It’s my mistake, I should have added a warning to say that the plugin is coded in such a way as to only work with PHP 5.3 and above.
You can check your PHP version by clicking the WooCommerce > System Status menu in your WordPress admin.
If you are running a lower PHP version, perhaps you might want to consider upgrading to a newer PHP version.
May I know the exact error you are seeing?
