When I view the source of my website, I am seeing this script inserted into my website. However I cannot find the template where it is being added.
This javascript html tag is inserted automatically by Weebly's backend server itself. It inserts it immediatly after the <head> element and before any items you have defined in your actual template file.
<script src="/gdpr/gdprscript.js?buildTime=1558379751&hasRemindMe=true&stealth=false"></script>
This code forces the display of the "This site uses cookies..." message that pops over the bottom part of the page. It also handles the user's selection.
It is inserted because Weebly itself forces your site to use cookies. It does this to enable its own collection of analytics on your homepage.
Yes. Code like this should be inserted after the site content.
You may be able have this removed by contacting Weebly directly.
