Hi @mbadrani,

I have the same issue with PS1.7.6.x
After clicking "Add button" => I reload the page => an exception displayed

Thanks!

Nice catch !

[mbadrani]

@matks & @khouloudbelguith I have another bug when I try to access to "orders/shopping carts" in the backoffice, it seems to be related bug wdyt?

[mbadrani]

both are calling CartRuleCalculator.php

[khouloudbelguith]

@mbadrani, I think they are related.
In my case all the shop FO is blocked with this exception, I don't have access to FO any more.

Thanks!

[mbadrani]

so If FO is not accessible anymore it's critical

@mbadrani please give more details:
With a fresh-installed shop, when I add a cart rule I can go through the checkout steps without interruption.
which sort of cart rule did you use ? Is it on a fresh install (which parameters) or after some changes (carrier, products...) ?
Your description is far too vague to reproduce easily.

@tomlev a complete description here on how to reproduce it:

Don’t forget to activate free shipping
I think it was the missing part, please share these details next time ^^

[tomlev]

it was. I can reproduce now

Furthermore, the problem is if you create a cart rule with free shipping AND a promo in % or amount.
A cart rule with only free shipping is working correctly
