Hi!
I think that you miss point 6 from installation instruction:
6. In admin/includes/database_tables.php
Add the following lines:
define('TABLE_EXTRA_FIELDS','extra_fields');
define('TABLE_EXTRA_FIELDS_INFO','extra_fields_info');
define('TABLE_CUSTOMERS_TO_EXTRA_FIELDS','customers_to_extra_fields');
or you miss point 11:
11. In catalog/includes/database_tables.php
Add the following lines:
define('TABLE_EXTRA_FIELDS','extra_fields');
define('TABLE_EXTRA_FIELDS_INFO','extra_fields_info');
define('TABLE_CUSTOMERS_TO_EXTRA_FIELDS','customers_to_extra_fields');
Check pleas these points and tell me result. If you have any
questions, don't hesitate - ask me.
Regards.
Marat.
