In MyStore configuration the following error is being displayed.

Warning: call_user_func(tep_cfg_get_zone_name): First argument is expected to be a valid callback in D:\hshome\tf735\lawnmowers-plus.com\admin\includes\functions\general.php on line 1232

Has anyone experienced this error before and know the fix? The version of OSC is 2.2 and has been installed from H-Sphere CP.

The error seemed to happen when the country was changed and the zone file cannot be updated.
