WordPress MU

Ok, so I developed some custom administration pages on WP single solution, which where using jQuery 1.3.2. And guess what.... wpmu is still on 1.2.8 :(

That means the admin panel breaks if I include jQuery 1.3.2.
That sux bigtime.

My solution will be to move the pages from backend admin panel, to frontend.

But in order to do this, I need to do the following:
- Login frontend (sidebar)
- Register new users with additional information

For the login, I'm thinking of using this plugin: http://wordpress.org/extend/plugins/sidebar-login/

When users register, I need additional data. I need something similar to http://skullbit.com/wordpress-plugin/register-plus.

I've looked at http://premium.wpmudev.org/project/set-password-on-wordpress-mu-blog-creation - but I'm not sure if this is correct for me. Users are not signing up to have new blogs, or being able to login backend.

Does anyone have experience on these matters?

Check #6 here and see if it relates to your jQuery version problem.

More importantly though, what version of WPMU are you running? 2.8.x includes jQuery 1.3.2. So does that mean you're running an older/vulnerable version?

I'm running the latest version, 2.8.4a.

I'm adding my jQuery like this:

wp_deregister_script('jquery');
      wp_enqueue_script('jquery', WP_SCRIPTS_URL . 'jquery_latest/jquery-1.3.2.min.js');

For all other java scripts, I use the following:

wp_enqueue_script('my-script', WP_SCRIPTS_URL . 'scripts/myscript.js');
