Hi, I have just updated a site with 7.02 which has thrown the layout of products.php & some of product detail, quantity selection & add to cart not functioning. Does this sound like a likely problem or would it suggest a dated version of PHP? My cpanel server info shows 5.4.45 but i have selected to use 5.6 with "PHP selector".
Can you let us know the URL so we can see what might be happening there? Part of the problem may be you are missing the ectcart.js line https://www.ecommercetemplates.com/support/topic.asp?TOPIC_ID=110209 but there's probably more to it than that from your description.
There's a bit of wacky css in there setting negative margins and other things. It would be difficult to do with a css snippet here so send me on your FTP details via email and I'll see if I can get the layout back again.
