Admin is "not allowed to manage these items"

PS: it’s working fine in WP 4.3.1, so the issue is occurring with WP 4.4-beta.

To fix this issue, in the function register_user_taxonomy() you have to add the show_ui-option to the register_taxonomy()-call and set it to true.

Here is the code (user-groups.php):

function register_user_taxonomy() {
    register_taxonomy(
        'user-group',
        'user',
        array(
            'public' => false,
            'labels' => array(
                'name' => __( 'User Groups' ),
                'singular_name' => __( 'Group' ),
                'menu_name' => __( 'User Groups' ),
                'search_items' => __( 'Search Groups' ),
                'popular_items' => __( 'Popular Groups' ),
                'all_items' => __( 'All User Groups' ),
                'edit_item' => __( 'Edit User Group' ),
                'update_item' => __( 'Update User Group' ),
                'add_new_item' => __( 'Add New User Group' ),
                'new_item_name' => __( 'New User Group Name' ),
                'separate_items_with_commas' => __( 'Separate user groups with commas' ),
                'add_or_remove_items' => __( 'Add or remove user groups' ),
                'choose_from_most_used' => __( 'Choose from the most popular user groups' ),
            ),
            'rewrite' => false,
            'capabilities' => array(
                'manage_terms' => 'edit_users', // Using 'edit_users' cap to keep this simple.
                'edit_terms'   => 'edit_users',
                'delete_terms' => 'edit_users',
                'assign_terms' => 'read',
            ),
            'update_count_callback' => array(&$this, 'update_user_group_count'), // Use a custom function to update the count. If not working, use _update_post_term_count
            'show_ui' => true
        )
    );
}

I did exactly as said:

I added ‘show_ui’ => true exactly as said.
I also tried ‘show_ui-option’ => true, but this did not work either.

function register_user_taxonomy() {
register_taxonomy(
‘show_ui’ => true,
‘user-group’,
‘user’,
array(
‘public’ => false,

But is does not work, I get an error. Plugin not working. error on line 333. unexpected …..

WordPress user are no programmers, I would appreciate a complete code or explanation. Thank you very much, in advance. And forgive me that I am just a user.

Lisa, I can confirm that Asgaros information is correct, by adding 'show_ui' => true the problem is solved.

Here’s a clearer way on how to add that line. I suggest to add it after line 314 (in the current version as of January 2016):

The original code looks like this:

array(
  'public' => false,
  'labels' => array(

Add your new line after 'public' => false, like this:

array(
  'public' => false,
  'show_ui' => true,
  'labels' => array(

After that, you will be able to access the admin area.

Kudos to you for taking a dive into PHP editing while being just a user ??

Thank you very much, that did work right away. I really apreciatet this precise instruction.
Cheers, lisa

I was pulling my hair over this, thank you!

Hi,

Could we have these fixes in the official repo and a new release please? ??

Is the development done on github? If so I would be happy to submit a PR if this would make the process smoother.

I just used the exact instructions from Manuel Schmalstieg to fix my occurrence of this defect. Thank you very much!

Thanks all—this has been updated in Version 1.3, just released!

I also added a Github repo so future contributions can be made there: https://github.com/katzwebservices/User-Groups

Thanks again.
