Overview

A number of the javascript libraries distributed with WordPress are also
hosted on Google’s AJAX Libraries API.
This plugin allows your WordPress site to use the content distribution
network side of Google’s AJAX Library API, rather than serving these files from your WordPress install directly.

This provides numerous potential performance benefits:

  • increases the chance that a user already has these files cached
  • takes load off your server
  • uses compressed versions of the libraries (where available)
  • Google’s servers are set up to negotiate HTTP compression with the requesting browser

For a more detailed look see Dave Ward’s 3 reasons why you should let
Google host jQuery for
you
.

Works with some modifications
by robkipa·1 year ago

Since this hasn’t been updated in forever, some modifications are needed to enable the plugin due to version checking. debug.log will show:

Not yet qualified with this version of WordPress. Bypassing UGL.

To fix: comment out lines 229-232 of use-google-libraries.php:

/*if ( version_compare( get_bloginfo( 'version' ), '4.8', '>=') ) {
self::debug( 'Not yet qualified with this version of WordPress. Bypassing UGL.' );
return;
}*/

I can confirm jquery.js then loads from Google’s AJAX library (tested on WP 6.6.2)

This Plugin is Outdated!

Plugin has not been updated in awhile – 6 years+
How to fix: WordPress post edit area – white text white background
You can actually select the white paragraph text to highlight it, and copy-paste it in a text editor, and fix the content or links – then paste it back. Just a quick, and live fix where WP’s displays white text on white background.
