Skimlinks not working

I have inserted my link from Skimlinks as per the instructions via the Skimlinks website under the footer in the advanced, settings, however nothing is working. I also tried to add a pop-up from Mailchimp into the header, but that never showed up either - so now, I just have the squarespace one. Ideally, I'd like the mailchimp one. What is going on with my site that's blocking the code in my header/footer area? 

 This is my website: adventureswithheather.com and this is the code in injected in the footer:

<script type="text/javascript" src="https://s.skimresources.com/js/141915X1606220.skimlinks.js"></script>

There is an error with that script on your site, so it's not going to work. You may need to disable Ajax Loading (via Site Styles) for your site to use an external script.
