Upgrade problem from 1.5.3.1 to 3.0.3.1

***edit from original post***
The problems that i have now updating from 1.5.3.1 to 3.0.3.1 is that i can not edit my products nor add new ones, when i hit edit or add new product, i get a blank page, what can ido?
And the other problem that i have is related to images on site and products and edit, i re-uploaded my images like it says in this post: viewtopic.php?f=202&t=205805&p=729542#p729542 , but now all my products, banners and categories are empty with no images, is there a way to automatically fix this without having to upload every photo again? I re uploaded my images through FTP service. Thank you

upgrading from 1.5 to 2.x or 3.x version is not simply like upload files. it is like a surgery "in database" you need to keep connections links trough database tables so my suggestion would be to hire someone:)

Thank you, but for now the only option I have is this forum, I hope someone can help me! The edit/add products is what I need to fix.

Well, don't worry, you will find many more problems, after trying the impossible,
by 'combining' old + new. But you won't find someone around here, making
your Shop work again as planned, if you have no budget, because it takes a Pro,
to make your Database 'understand' your new OC Version 'way of doing things'.
This, because, if everything would still work the same, there would be no need for
something new ...

Good Luck!

i fixed the edit/add product problem, but now i have a new one, when i make an order on my site, the price of the order is always $0 and no email is generated to admin or client. What can it be?
