222933 Oscommerce site mysql5 error

Hi there, mysql has been updated and caused some problems to my oscommerce website, [login to view URL] I am getting an error when I try to click on a product: 1054 - Unknown column 'p.products_id' in 'on clause' select count(p.products_id) as total from products_description pd, products p left join manufacturers m on p.manufacturers_id = m.manufacturers_id, products_to_categories p2c left join specials s on p.products_id = s.products_id where p.products_status = '1' and p.products_id = p2c.products_id and pd.products_id = p2c.products_id and pd.language_id = '1' and p2c.categories_id = '49' [TEP STOP] The oscommerce script is heavily modified, so a simple replace can not be done. Apparently there are patches and fixes avaialble. Thanks very much. Michelle.
