Wordpress Custom Post Types doesn't show in admin left sidebar menu

Question

I have a weird problem with one of my custom post type that doesn't show in left sidebar admin menu.

I declared 5 custom post types but the fifth doesn't show in left menu. Here it's the Clients post type that doesn't show. I made a lot of search about this, without success.

Thanks a lot for your help !

Answer 1

This case does not seem to be the same, but one reason for not showing in the left admin menu is the length of the name of the post type is longer than 20 characters Function Reference/register post type

Answer 2

In my case I was able to see the custom post type in the left side bar as administrator but the authors could not. What I had to change was the capability_type from page to post since that's what authors are enabled to by default.

'capability_type' => 'post'

This line goes in the in the $args array of the definition of the post type.

Answer 3

Sometimes this can be caused by the menu_position clashing with another menu position, or perhaps being hidden away by some other plugin. Try changing that value.

'menu_position' => 21

Answer 4

if you use User Role Editor plugin it is sometimes needed to add ("Users" -> "User Role Editor" -> "Add Capability") some custom capabilities like: 'read', 'edit_post', 'delete_post', 'read_post' by hand to be able (to have rights) to see your custom post

Answer 5

Add 'show_in_menu' => true, after 'public' => true,

Answer 6

Add code on your function.php.

See the below defined image:

Answer 7

I just had the same issue, and nothing helps for me. But I found a solution (temporally), I go to Appearance > Customize and there it was, Custom post type was there. I don't know what causes this bug because in localhost everything was fine, but on live, it's not working.

Answer 8

You may have just set the required attributes to false. These attributes must be set to true in order for the custom post type to show in the WordPress admin menu on the left:

'show_ui' => true,
'show_in_menu' => true,

Answer 9

If this is only happening on one specific user account, but it's working on all others, then you'll need to have the user that this is happening to do the following:

From the menus page, go to "screen options" in the top right corner, and then check and uncheck your custom post type. This refreshes something internally, and fixes the problem. If upon clicking "screen options", you don't see your custom post type listed, then you need to use one of the other solutions posted here.

Answer 10

Your custom post type name accept only 20 charactor, see below example, now it is showing in admin panel at left side register_post_type( 'artedu_post_type', $args );

It was not visible when it was register_post_type( 'arteducation_post_type', $args );

Answer 11

Using WP-CLI this job is easy. First create the desired custom post type:

wp scaffold post-type team-member \
  --label='Team Member' \
  --dashicon='id-alt' \
  --theme

At end, do not forget add to functions.php file:

cat << EOF | tee -a $(wp eval 'echo get_theme_file_path("functions.php") . "\n";')

/**
* Custom Post Types.
*/
require get_template_directory() . '/post-types/team-member.php';

EOF
