Download the files above and extract 'admin_import.php' and 'admin_table_users.php' in /admin folder of your shop replacing existing files. Please do not forget to make a backup copy of the current files in case something goes wrong.

Does this patch also fix an issue with exporting users whereby not all the field in the va_users table are available for export.
 
I am specifically interested in the field "user_site_url" which is not shown in the list of exportable field and adding a custom field {user_site_url} still does not export that fields contents
