I solve this problem by running the following requests in my phpMyAdmin,
one)
INSERT INTO `eav_attribute` (`attribute_id`, `entity_type_id`, `attribute_code`, `attribute_model`, `backend_model`, `backend_type`, `backend_table`, `frontend_model`, `frontend_input`, `frontend_label`, `frontend_class`, `source_model`, `is_required`, `is_user_defined`, `default_value`, `is_unique`, `note`) VALUES(140, 3, 'thumbnail', NULL, 'catalog/category_attribute_backend_image', 'varchar', NULL, NULL, 'image', 'Thumbnail Image', NULL, NULL, 0, 0, NULL, 0, NULL);
2)
INSERT INTO `catalog_eav_attribute` (`attribute_id`, `frontend_input_renderer`, `is_global`, `is_visible`, `is_searchable`, `is_filterable`, `is_comparable`, `is_visible_on_front`, `is_html_allowed_on_front`, `is_used_for_price_rules`, `is_filterable_in_search`, `used_in_product_listing`, `used_for_sort_by`, `is_configurable`, `apply_to`, `is_visible_in_advanced_search`, `position`, `is_wysiwyg_enabled`, `is_used_for_promo_rules`) VALUES (140, NULL, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, NULL, 0, 0, 0, 0);
3)
INSERT INTO `eav_entity_attribute` (`entity_attribute_id`, `entity_type_id`, `attribute_set_id`, `attribute_group_id`, `attribute_id`, `sort_order`) VALUES (337, 3, 3, 4, 140, 3);
Here I use id_attribute as 140, use the identifier for this in these queries using a unique value
