Thanks for writing in!
I checked the website and can see the error message. However, the script is getting loaded from Github repository. Here's the source URL https://kenwheeler.github.io/slick/slick/slick.js.
Are you using any tool that's loading script from above URL. I Googled and can see that the kenwheeler Github page has bunch of jQuery scripts. Please note that issue coming from 3rd party scripts fall outside the scope of support we can offer.
Unfortunately, you can't change the email address. Can you let me know the reason for changing the email address. If you want the licence to be associated with new email address then please follow along:
- You can unlock the license from this account. After that create a new account using new email address and register the licence in that account.
Please take a look at following resource for more information:
