[Fixed v1.5.1] Fatal error: 1062:Duplicate entry '1-1' for key 1 adding option values

[Ajeh]

If you have not added any Option Values yet, you can rebuild the table products_options_values with:

TRUNCATE TABLE products_options_values;
INSERT INTO products_options_values (products_options_values_id, language_id, products_options_values_name) VALUES (0, 1, 'TEXT');
