New Content type is not listing in Add Content in Drupal 7

Question

When create custom content type through UI or programmatically in Drupal 7, there is no link is listed in the Content > Add content.

I was creating the content types without any trouble, but now it is created(succes message is showing) when I check them in the node_type table but not lising in the admin/structure/types.

But no content type is listing(not any links showing) in the Content > Add content, or Structure > Content type administration menu.

Here is the code that allows users to access node pages:

/*
 * Allow users to view the contents
 */
function mymodule_node_access_records($node){
    $grants = array();
    $grants[] = array(
        'realm' => 'example_realm',
        'gid' => 123,
        'grant_view' => 1,


  'grant_update' => 0,
    'grant_delete' => 0,
    'priority' => 0,
);
return $grants;
}


/**
 * Implements hook_node_grants().
 */
function mymodule_node_grants($account, $op){
    $grants = array();
    if ($op == 'view') {
        $grants['example_realm'] = array(
            123,
        );
    }
    return $grants;
}

Then I rebuild permissions using Content Access module.

Answer 1

1. Check the permission for node creation of that type in admin/people/permissions
2. Clear all caches and retry and it should be OK
