Hello @preoteasa ,

PS 1.7.8.x is already compatible with PHP 7.4 : https://devdocs.prestashop.com/1.7/basics/installation/system-requirements/

I'm using PHP 7.4 with PS 1.7.8.5.
I can't reproduce your issue, i do not have any error :

Can you give more info about your issue ?
Thanks!

Here is a link where you can test the erroneous behavior:

--deleted-- check the video later.

It is a new install of Prestashop 1.7.8.5 on Ubuntu 20.04 LTS, using apache and php 7.4.3, cgi. It is the default installation of php.

$php --version
PHP 7.4.3 (cli) (built: Mar 2 2022 15:36:52) ( NTS )

The shop runs on AWS on an ARM processor.

By the way. If you enable debug mode, the error goes away and you get the output from your screen shot. I think that this is a serious problem too. The debug mode should not hide errors.

@preoteasa ,

I have indeed reproduced your issue with PHP 7.4 on PS 1.7.8.5 (downloaded here)

• With PS 1.7.8.x branch, there's no issue. I tested with PHP 7.3 and PHP 7.4.

• With PS 1.7.7.8 and PHP 7.4, the error is here too. But that's normal because PS 1.7.7.8 is not compatible with PHP 7.4. With PHP 7.3 it is OK.

• With develop branch, it works well with PHP 7.4 too.

So you can reproduce the error with 1.7.8.5. What is changed in 1.7.8.x branch? I checked the source code of development branch and it seems similar to 1.7.8.5 release. I could attempt to test the development branch as well. Are you sure the debug is off?

1.7.8.5...1.7.8.x

The error occurs also in the development branch of Prestashop. I just cloned the development branch. Here you can see the error:

--deleted-- check the video later

IN ORDER TO REPRODUCE THE ERROR, THE DEBUG MODE MUST BE OFF.

Here it is a recording that shows the error for the development branch.

I will take down the test installation.
