To optimize the website and to remove a couple of errors on the website

Hi all, we have a website he made through multisait (not to be confused with multilang!!)

need to get him back in the green paint on guglipid to 90

and there is an error associated with the order when the transition to the page order and choose the delivery method then there is a crutch - perclick these ways, and sometimes it does not work - it needs to be corrected to the methods of delivery was placed from the admin panel and the order it is attached. Depending on the selected shipping method in the invoice is included or not included the shipping cost - it should work correctly after fxa is now a little bait because pereklita at the last step or because of what is not entirely clear.

Email templates should contain all of the old order - that pokupaly that the admin.

thank you welcome your suggestions on cost and time
