JavaScript Error (Uncaught TypeError: $.initNamespaceStorage is not a function)

We are running a Magento multi site and on ONE site only, I get this error Uncaught TypeError: $.initNamespaceStorage is not a function

All sites use the same theme (just some differences between them..), any clues ?

Thank you for helping me Here is the script

        require.config({
            deps: [
                'jquery',
                'mage/translate',
                'jquery/jquery-storageapi'
            ],
            callback: function ($) {
                'use strict';

                var dependencies = [],
                    versionObj;

                $.initNamespaceStorage('mage-translation-storage');
                $.initNamespaceStorage('mage-translation-file-version');
                versionObj = $.localStorage.get('mage-translation-file-version');

                 if (versionObj.version !== '92817ddfc8670bafd7f41084a570359ae57c4623') {
                    dependencies.push(
                        'text!js-translation.json'
                    );

                }

                require.config({
                    deps: dependencies,
                    callback: function (string) {
                        if (typeof string === 'string') {
                            $.mage.translate.add(JSON.parse(string));
                            $.localStorage.set('mage-translation-storage', string);
                            $.localStorage.set(
                                'mage-translation-file-version',
                                {
                                    version: '92817ddfc8670bafd7f41084a570359ae57c4623'
                                }
                            );
                        } else {
                            $.mage.translate.add($.localStorage.get('mage-translation-storage'));
                        }
                    }
                });
            }
        });
