404 issues with unminified JavaScript and CSS files

Shopify Discussion
,

Topic summary

Main issue: A site audit reports “404 issues with unminified JavaScript and CSS files.” The poster believes this causes visual instability, slow performance, a high HTML-to-text ratio, and a low PageSpeed Insights score, and requests help to understand and fix it.

Clarifications:

  • 404 indicates requested files are missing or paths are incorrect.
  • Unminified JavaScript/CSS means code isn’t compressed, which can increase file size and slow rendering.

Current actions:

  • A helper asked for the store URL to investigate.
  • The URL (www.infraredheatingsupplies.com) was provided.
  • The poster followed up, asking if the review was completed.

Status:

  • No diagnosis or solution has been shared yet.
  • Discussion remains open, pending analysis of the store to locate broken file references and assess performance impacts, then propose fixes (correct file paths, restore missing assets, or implement minification).
