Menu feature – drag and drop is not working

Anyone… help… Is it a wordpress bug?

i had issues with draggable items clashing with a couple of plugins in the past (including shadowscript js and tinymce). first thing i would try to disable all plugins and see if it works, then you can figure out which plugin is breaking the menu

Thanks psycolor for your help, but i don’t have a single plugin istalled. So not that is the problem.

I am having this same problem. Did you find a solution VladNovo?

Try adding define('CONCATENATE_SCRIPTS', false); to your wp-config.php file, just below the define('DB_HOST line.

James, tried it, doesn’t work, still can’t drag and drop menu items in the proper places. This was working, must have been a recent upgrade on one of the plug-ins, will try to shut those down and see if it works again.

I just had this issue just happen yesterday in one of our 3.0 projects, I am upgrading to 3.0.1 now and hope this will fix it.
Looks like a bug to me, as other projects in 3.0.1 work fine

I just found the problem on mine. It is a plug-in conflict with LBAK User Tracking. I deactivated it and everything worked fine. Once I made my changes I activated it again.

If it was working in the past, deactivate any newer plug-ins you installed or any you might have upgraded. It might work for you as it did for me.

I had the same problem, but I found the solution.
It is a javascript (jquery) problem. In my child theme, I had the following code

add_action('init', 'my_init_method');

my_init_method loads my js and css files:

function my_init_method() {
  wp_deregister_script( 'jquery' );
  wp_register_script( 'jquery', 'https://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js');
  wp_enqueue_script('jquery');
  ...

the problem is that the funcion is called from admin panel, too.
So I changed as follows:

if(!is_admin()){
  add_action('init', 'my_init_method');
}

Now it works fine. Hope to be useful.

I’m confused by these posts – is this really a theme-related issue, or a plug-in issue? Upgrading to 3.0.4 did not fix the problem. Is it a java script issue that can be caused by any theme or plug-in using java script? If theme, where do I find the code indicated by cxd? I am not php-savvy.

Nevermind – in my case it’s an offending plugin: Social Discussions by LinksAlpha. Deactivate it, and the menus work again.

in a theme you should find this code (if it exists) in wp-content/themes/youtheme/functions.php

cxd is absolutely correct. This same issue happened to me just recently and was baffling me.

If you have added a function to your functions.php file to load jquery from Google’s CDN, then make sure you’re NOT calling it in the admin area.

Thanks for the solution cxd!

@cxd also helped me resolve this issue. The WordPress Codex does make note of adding the ‘if(!is_admin) { … } ‘ in the documentation. This is required to prevent the drag-and-drop in the custom menus from breaking.

to fix this just wrap the jquery lines in function laecho_main of social-discussions.php starting at line 773 with if(!is_admin()){ like this…

if(!is_admin()){
	wp_register_script('lajquery', 'https://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js');
	wp_enqueue_script ('lajquery');

	wp_register_script('jqueryuijs', 'https://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/jquery-ui.min.js');
	wp_enqueue_script('jqueryuijs');
	}
