Es un problema que hace en la consulta sql al entrar en una categoria:
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 = '3' and p2c.categories_id = '24'
he mirado todas las tablas una a una y todas tienen esa dichosa columna.
