It may be obvious to you or to someone who is knowledgeable in coding but not to me I'm afraid. If it was, I wouldn't be posting questions here but answers. Anyway, there still seems to be a problem:
QuoteError: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'to = '2023-02-23 16:14:50' WHERE id_specific_price = 18' at line 1
Using PHP version: 7.4.33 and 10.6.12-MariaDB if that makes any difference.
