oscommerce site giving 1054 - Unknown column Error

hey guys i switched my site to new web hosting provider and after i have uploaded teh site to new host. i was getting this error when i visit product category page 1054 - Unknown column 'p.products_id' in 'on clause' select distinct p.products_id, p.products_image, p.products_tax_class_id, [login to view URL] as specstat, s.specials_new_products_price, p.products_price from products p left join specials s on p.products_id = s.products_id, products_to_categories p2c, categories c left join featured f on p.products_id = f.products_id where p.products_id = p2c.products_id and p2c.categories_id = c.categories_id and c.parent_id = '5' and p.products_status = '1' and [login to view URL] = '1' order by rand() DESC limit 6 [TEP STOP] olny two things i could think of changed. 1) my older host had mysql v 4.1 and the newer one upgraded me to 5.0 also im having problems viewing my admin side. Like the files are not viewable.. i just see blank white page... may be i have entered the wrong path. nways can some one please fix these issues for me. thankyou
