## JavaScript errors on load

Passing looks like: No JavaScript errors while loading the page.

**Why it matters.** Each error means a script stopped part-way, so a slider, form or tracker may silently not work for some visitors. Errors also cost time on the main thread.

**How to fix it.**

1. Open the technical detail, then the browser console (F12) on the page, and fix the errors from the top; the first one often causes the rest.
2. Check for plugins or scripts that were removed but are still referenced.
