Javascript execution in MU

I've reproduced this issue on 4 separate MU installs. I'm trying to use a jQuery slider, but keep getting an undefined method error.

I'm enqueueing scripts according to the wordpress docs. I can see that the scripts are being loaded through the Chrome developer panel. When the method is called on an element, it produces a undefined method error. I can verify that the javascript that powers the slider is being run because I put alerts before and after it and saw both of those. If I run the slider method declaration from the console in the developer panel and then call the slider function on the element, everything works. So, it seems that the JS is running, but is then somehow being reset.

To confirm that this is an issue with MU, I can disable MU and just run my main site. When I do this, without changing any code, the slider works as expected.

I've tried enqueueing the scripts on a variety of actions including wp_head, init and template_redirect.

I've had this same javascript issue with all libraries I've tried to add. This issue can be reproduced easily with a single user instance of wordpress by installing the anything slider plugin, add some jQuery like:




confirm that the slider works, go through the steps to enable MU. The slider should be broken after that.

The error is:

Uncaught TypeError: Object [object Object] has no method 'anythingSlider'

The anything slider plugin is enqueuing all of its javascript files. I'm enqueueing the javascript on my front page like this:

wp_enqueue_script('front-page', get_bloginfo('template_directory') . '/js/front-page.js', array('jquery'));

This is the entire contents of front-page.js:


I've attached my front page template and the javascript enqueued on that page.

I've found what I believe to be another instance of this issue.

The create link button of the visual tiny MCE editor causes a javascript error when MU is enabled.

The exact error is "Uncaught TypeError: Object [object Object] has no method 'wpdialog'"

The editor works as expected with MU disabled.

I can't reproduce the TinyMCE error. Have you tried with a brand-new installation with no plugins and the twentyeleven theme?

My apologies - I've found the issue.

I have a custom plugin that was adding the google API jquery in a function called by the shutdown hook. So, the javascript execution error was entirely my fault.

I may still have found a bug in how MU and single user act. This issue went away in a single instance. So, it seems that MU is firing the shutdown hook differently than single user.

Once again, sorry for the false alarm.

Ok, feel free to open a new ticket if you pinpoint the shutdown issue.
