The above solutions make absolutely no sense.

The only right solution is to block the concatenation of scripts:

add in wp-config.php:

define(‘CONCATENATE_SCRIPTS’, false);

That works.

Thanks for your help
Was pulling my hair out having problems with script errors.

“Re upload the wp-includesjs folder and overwrite whatever is in there.
That’s what fixed it for me”

Worked first time.

Saved me a lot of grief.

I found that my in my Theme functions file there was an extra few lines trying to change the jQuery files.
For example in ./wp-content/themes/twentyten/functions.php near the bottom:

function my_init_method() {
wp_deregister_script( ‘jquery’ );
wp_register_script( ‘jquery’, ‘http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.js‘);
wp_enqueue_script( ‘jquery’ );
}

add_action(‘init’, ‘my_init_method’);

I believe these were added by some plug-in. Just comment them out and the jQuery should function again. My problem was on the menu editor under appearance. I couldn’t drag the menus about.

Thank you! I am new to wordpress and I am just trying to create my new wordpress theme. Why not use multi-level menus to start with? So I wantet to use jquery as with many themes the hover attribute of li was used to style the second level of ul, but that does not work in IE 6.
I just could not use jquery at all, till I have found your blog. I have udated it once to verion 3.1, so that might have caused the problem!

THANK you so much for spending the time to do that research. I was just starting on the same process myself when I stumbled upon your post here, and overwriting the contents of the js folder did the trick just as you said it would.

CHEERS~! Sylvia
