WOOCOMMERCE URGENT ISSUE TODAY

Urgent issue needed to be resolved in woocommerce unfortunately been massively let down by a developer who has tried to fix a cart not updating and has now managed to force a login to worpress to add to cart and now we cant even get anything in the cart. This MUST be fixed today, do not apply if you don't have extensive woocommerce background. This was taken on by another PPH person last friday as an urgent task and has now been made worse nearly a week later!
