I have the latest version of the OS Commerce and recently I changed from servers, since that change, I have 2 problems:
No.1: the most purchased products module won't show any products, it appears blank, just the title.
No.2: I have also the problem that when a product reaches 0 in stock it should not appear any more on the store, but it keps showing and it even allows customers to buy them even there is a big sign with red letters that say SOLD OUT but some customers just place their orders and pay for them making me return their money and give lame explanations on why this happened.
Can anyone point me on the right direction to fix that? I am new to this and need step by step help. Thank you so much!
