I have the same issue, but provider does not offers 7.3 anymore .. Shop upgrade is difficult because of template and different modules... any other idea? by changeing product template?

Either change template or hosting. Create new prestashop installment with new / old template. Install modules and if all works fine, migrate whole data from old one instead of upgrading on live shop.
