How can I fix a 404 error caused by a missing CSS file?

Hi,

I’m analysing my website speed and I can see that a particular CSS file is leading to a 404 page result, which is slowing down my page.

This is the URL: https://cdn.shopify.com/s/files/1/0524/3712/3270/t/9/assets/jquery.fancybox-1.3.4.css?1698

Apparently the asset doesn’t exist, and I’m wondering how to fix it?

Add this to extension to chrome

https://chrome.google.com/webstore/detail/shopify-theme-search-by-b/epbnmkionkpliaiogpemfkclmcnbdfle?hl=en

Go edit your themes file.

Search for jquery.fancybox

Find the link and remove it

Check for errors

Thank you so much, that’s helped!
