Unable to load icon for carrier on admin side

[insitweb]

Hello,

I have an error when I want to upload an icon for a carrier. It is impossible for me to download this icon from the administration.

here is  error message :

jquery.ajaxfileupload.js:6 Uncaught TypeError: jQuery.handleError is not a function

The "js/jquery/plugins/ajaxfileupload/jquery.ajaxfileupload.js" file is minified, so it's very difficult to read it.

I tried in Php 7.1 + 7.2 + 7.3 but it doesn't change anything.

Has anyone encountered this problem before and found a solution?

Thank you in advance for the time you devote to me.

Prestashop 1.7.8.3

PHP 7.2

For 1.7.8.3 you need to use PHP 7.4. Try this first.

Hello ComGrafPL,

Thank you for your advice but unfortunately it does not work in Php 7.4.
