Hi Ade

I'm posting here – if you don't mind – my method that I found working after I got a black box when got upgrade to the newest version.

In short: WP 3.0.1, changing to Mootools didin't help, also downgrading…

So I checked the source code of my site and found that I have a double include of jQuery libs.
One from WP include and another one from Google CDN that I put some time ago in functions.php. Deleted that and It works now :)

PS. For users that want to have jQuery or Mootools from CDN just install the "Use Google Libraries" plugin. It replace WP jQuery with the Google hosted one.
It works too with DCC :)

Thanks for great plugin!

Hi,

Thanks for posting this. Glad you like the plugin! Smile

A quick word about loading javascript libraries (such as jQuery) in Wordpress, which may be of interest to others.

1. Plugins should always load jQuery (and other libraries) using the WP function wp_enqueue_script(). The cool thing about this function is that it checks whether jQuery has already been enqueued by another plugin, hence avoiding double loading. However, for this to work, all plugins should use wp_enqueue_script() – which is not always the case.

2. Some WP users want to use javascript functionality in a theme, without it being a WP plugin. This is fine, of course, but again for reasons of good practice and to avoid double loading, use wp_enqueue_script to call your javascript library.

3. The DCG uses wp_enqueue_script(). So, as long as other plugins on your install do the same, there will be no double loading.

Hope this makes sense and that it is of use to other readers.
