Hi @Peter4661,

Could you please add steps to reproduce the issue in a new comment.
Thanks!

[Peter4661]

Customer complaint he did not recieve order confirmation.

We tried to reproduce it by placing order ourselves.

In last payment step, selecting payment method "bank transfer", 500 error when confirming order.

With debug, on putting product in shopping cart, did get result as shown above.

Order has been processed in backoffice. No order confirmation revieved.

Issue solved after installing php-intl extension!

[Peter4661]

Backoffice alos now sends order messages correct!

Still this bug on PS 1.7.6.0

@matteolavaggi, php-intl extension is installed on your server?

Thanks!

[matteolavaggi]

Yes, i've found the problem, is related to the count() function modification on php7.2 that now retunr an e warning.

THe problem is related to this module , developer has not yet fixed it (crazy)

Free Delivery Pro

BTW because prestashop is full of third parts module , why there isn't a check against php compatibility of them? OR better there is no way to implement a better handling of the error send back from count() function in dev mode? thanks

For now i've fix the dev capability changing the function to @count , and ask developer to do therir job.

elseif (@count($product_list)) {

@matteolavaggi, As it's not a module provided by Prestashop, we can't do anything with this.
You should contact the module author via your addons.prestashop.com account, they are the only ones to help you with it.
Thanks!

Unfortunately there are no reliable ways to be able to say "this module is php7.2 compatible". There are lot of tools that can find php7.2 errors in a php code, but no tool can confirm there is absolutely zero issues in it. This is the responsibility of the module developer to handle different php versions, or to warn users what versions are not compatible.

BTW this module is really late 😄 php 7.1 will be End Of Life in 2020 so he better hurry to be php7.2 compliant and php7.3 compliant
