"If your're using chrome:
1. reload a page
2. press F12 (it will open 'developer tools' window at the bottom of your screen)
3. Click 'Console' at the top-nav tab
4. Click on the edit icon on the page and see if any error will be displayed in the console."
I did as you said and there are these errors:
"Failed to load resource: the server responded with a status of 404 (Not Found)
http://www.host-ecommerce.com/system/js/external/jquery/plugins/cookie/jquery.cookie.js
Uncaught TypeError: Object function (e,t){return new x.fn.init(e,t,r)} has no method 'cookie' adminPanelInit.js:8"
Please, What can I do?
Thanks in advance
