Our site has become really slow to load. We had a designer help us set up the site over 3 years ago and it's been fine until recently. I reached out the support and they flagged this offending code from our homepage header:
<link rel="stylesheet" href="https://vassil.org/nz.css">
I checked and the site in the href is no longer up. I found a copy of the stylesheet in the Wayback machine. Can I host this code on the Squarespace site or does it need to be external to Squarespace? could I use dropbox to host it?
Thanks
