[360noscope]

jquery-confirm version: v3.3.3

I'm submitting a ... (check one with "x") [x] bug report [ ] feature request [ ] support request

Current behavior: $.alert is not working on code when using downloaded version of jquery-confirm from website.

Expected behavior: $.alert should popup modal correctly

Steps to reproduce:

• Download and include all needed file in page on head and script tag

Related code:

$.alert({
                    title: 'Error!',
                    draggable: true,
                    icon: 'fas fa-exclamation-triangle',
                    content: 'ไม่พบชื่อผู้ใช้ดังกล่าวค่ะ',
                    containerFluid: true,
                    type: 'red',
                    typeAnimated: true,
                    buttons: {
                        ปิด: function () {
                        }
                    }
                });

Other information: When i changed to cdn version of jquery-confirm its working so i suspected that download version still got some bug on it. Browser: Firefox 67.0
