Also, there is a bit of code in your source that is not right. You might recognize it as it seems to come from a theme (or plugin) option:
<script>
/**
* Write your custom Javascript code here.
*/
<script id="mcjs">!function(c,h,i,m,p){m=c.createElement(h),p=c.getElementsByTagName(h)[0],m.async=1,m.src=i,p.parentNode.insertBefore(m,p)}(document,"script","https://chimpstatic.com/mcjs-connected/js/users/b7541e33036b766afb28af2b4/c5377ac02a9b1f2d1e7178e30.js");
</script>
</script>
You need to remove <script id="mcjs">
and </script>
from that option field as the output is already wrapped in script tags. If the chimpstatic code MUST have an ID, then it should be placed in a Custom HTML widget or be hard coded in your theme footer.php (or otherwise inserted)
