  • you can try it by either updating the browser version. Before that try to clear your browser cache and magento cache.

Last error solution:-

Uncaught TypeError: Cannot read property 'timepicker' of undefined

means that


is undefined. So, you probably have not included jQuery UI.

Try to include it before any of your scripts (except jQuery itself).

  • ok but when i refresh its work

  • @Arjun I am facing same issue so where can i include jQuery file in my website? Aug 17, 2018 at 10:44

Have you written any custom javascript? As the answer answer states you have an issue with jqueryui. Although to explain further you shouldn't need to include jquery or jquery ui. Just use requirejs to load it for you. For example

], function($) {
    $.widget('vendor.customAccordion', $.mage.accordion, {
        someAction: function(element) {
            // your code here
