Better WordPress Minify version 1.2.2 does not yet support protocol-relative URLs, but the next release is supposed to correct this.
I've had reports of Gravity Forms breaking UGL, but I don't have access to Gravity Forms, so I'm not sure what's going on. If you need Gravity Forms you might need to disable UGL, or it might be fine, I'm not really sure.
WP-Minify doesn't yet support protocol-relative URLs. Add '//ajax.googleapis.com/' as a JS and CSS exclusion.
I've had scattered reports that UGL is stepping out of the way when using K2.
If you're going to flag the plugin as "broken" in the WordPress Plugin Directory, please try and let me know what is broken. I'm not a mind reader.
Use Google Libraries uses the following hooks (each with a priority of 1000).
Use Google Libraries compares it's list of supported scripts to those
registered, and replaces the standard registrations
src with ones that
point to Google's servers. Other attributes (like dependencies) are left
Use Google Libraries removes the
ver=x.y.z query string from the URL
used to load the requested library if it is going to load the library from
. Otherwise the URL is left unaltered. This both improves the chances of the given URL already being cached, and prevents script.aculo.us from including scripts multiple times.
Parts of this plugin (specificly, the dropping of the micro number, which has since been removed for better caching performance) were inspired by John Blackbourn's Google AJAX Libraries, which has very similar goals to this plugin.
