Prestashop: Conflicting free shipping discounts causing "no carriers available for your delivery address" at checkout

[OdeChan]

Hi there!
This issue might relate to these bug reports that I found (but I don't think they are exactly the same): #11172, #10903

In Prestashop 1.7.6.7, when trying to create two "free shipping" discounts, which one has a minimum amount conditions, no shipping method show up in checkout and instead there is "Unfortunately, there are no carriers available for your delivery address."

Steps to reproduce:

1. Add cart rule of "Free Shipping":
   -- Information:
   
   -- Conditions:
   
   -- Actions:
   
2. Add a second cart rule for a specific user:
   -- Information:
   
   -- Conditions (user is crossed out but is needed, shipping can be excluded or included):
   
   -- Actions (the "apply a discount" does not matter here, it can be set to a lower percent or set to "None"):
   
3. Add a products to the cart that are less than cart rule 1 amount (i.e 100 ILS) and add the discount code:
   
   The conditions of cart rule 1 are not met and therefore do no apply, while cart rule 2 is applied and price changes as need be.
4. Advance to address selection and finally to shipping method, where the issue resides:
   

Other tests:

• I tried disabling the "Free Shipping" cart rule (1), which brought back the shipping methods for cart rule 2. Of course this means I cannot offer my customers free shipping on orders over X amount.
• Cart rule 2, while now was just meant for testing, has a use case of offering individual customers free shipping on any amount. The ability to do this is of course impacted if they cannot choose a shipping method.
• Adding an additional user-specific cart rule with free shipping (whether or not has minimum amount condition) does not impact cart rule 2 and shipping methods show properly.
• Adding products that total > 100 ILS (cart rule 1's condition) works normally and shows shipping methods even if cart rule 2 is applied (cart rule 1 applies automatically and they stack).
  

Additional information:

• PrestaShop version: 1.7.6.7
• PHP version: 7.3

Please let me know what other information I can and should provide to assist with this issue :)

Hi @OdeChan,

Thanks for your report.
I manage to reproduce the issue with PS1.7.6.8.

But it is fixed with the next release 1770.
I tried with PS1770rc1build1 => ok

I attached a screen record

Thanks!
