PS4 and eCart 5.0.2
I had a few teething problems when PS3 came out and replaced the code in WA_Store_Cart_PHP and the Definitions file with the rules I wanted.
I tried to do the same in PS4 but that didn't work for me.
I tried using eCart 5.0.2 to created a zero ship value for items under 0.2kg, a value for sub 5kg packages and a value for greater than 5kg. eCart wouldn't modify the WA_Store_Cart and wanted to create a new Cart object. It looks like it takes the values from either the PS3 upgraded store (to PS4) or the current PS3 site.
I've attached the PS3 working store files (ridewerx.com/store), the PS4 store files (ridewerx.com/shop) and the eCart created files.
Can you please provide some guidance in bug fixing this?
