jQuery Migrate is loading

jQuery Migrate is a compatibility layer for plugins and themes written for very old versions of jQuery. Most up-to-date sites don't need it, but WordPress still loads it by default on the front end.

Why it matters

It's usually render-blocking because it loads right after jQuery in the <head>, delaying first paint on every page.

How to fix it in WordPress

  1. Make a backup or use a staging site first.
  2. Install a code snippets plugin and dequeue jquery-migrate on the front end, or use your performance plugin's option.
  3. Click through your menus, sliders, forms and popups to confirm nothing broke.
  4. Clear your page cache.

Perfmatters

  1. 1Go to Settings → Perfmatters → General.
  2. 2Toggle on 'Remove jQuery Migrate'.
  3. 3Save, clear cache, and test interactive elements (menus, sliders, forms).

How to verify the fix

  • Open your browser console on several pages and check for JavaScript errors.
  • Confirm jquery-migrate.min.js no longer appears in Maki's request list.

Be careful

  • Older themes, sliders and page builder add-ons may rely on jQuery Migrate. If something breaks, turn it back on.
