WordPress: User with custom role cannot access wp-admin - wordpress

Question

First of all I am a WordPress learner. So sorry if my code looks stupid!
I have created a custom theme with a custom user role. I am not developing any plugin.
In my fucntions.php file I have written the following code to create a User role. Users assigned to this role are supposed to login to the admin but only be able to access their Profile pages.
add_action('init', 'yrc_cst_register_role_customer_service_rep');
/**
* Register new user role
*/
function yrc_cst_register_role_customer_service_rep() {
$wp_roles = new WP_Roles();
$wp_roles->remove_role('subscriber');
$wp_roles->remove_role('editor');
$wp_roles->remove_role('contributor');
$wp_roles->remove_role('author');
$service_rep_caps = array(
'read' => false,
'create_posts' => false,
'edit_posts' => false,
'edit_others_posts' => false,
'publish_posts' => false,
'manage_categories' => false,
'manage_options' => false,
);
add_role('customer_service', __('Customer Service'), $service_rep_caps);
}
I have removed all roles except Administrator, because no other role is required for this portal. Administrator will only create Users with Customer Service role.
I have no third party plugin installed in the system.
Users with the custom role are able to login to the system through a custom login page which is working OK. But whenever they are trying to access their Profile page the following error message comes up:
Sorry, you are not allowed to access this page.
Is there anything like 'edit_profile' => true?
I must be doing something wrong but my limited knowledge is not enough to figure this out. Any suggestion would be highly appreciated.

Answer 1

You might be able to do it like this :
This should clone the subscriber role capabilities and create your role for it.
add_action('init', 'CreatecloneRoleSubscriber');
function CreatecloneRoleSubscriber()
{
global $wp_roles;
if ( ! isset( $wp_roles ) )
$wp_roles = new WP_Roles();
$sub = $wp_roles->get_role('Subscriber');
//Adding a 'new_role' with all subscriber caps
$wp_roles->add_role('customer_service', 'Customer Service', $sub->capabilities);
}
EDIT : Read discussion in question comments

Just change the manage_options to true in your case
But note that by allowing manage_options to true, those user will have access to other parts of dashboard as well
$service_rep_caps = array(
'read' => false,
'create_posts' => false,
'edit_posts' => false,
'edit_others_posts' => false,
'publish_posts' => false,
'manage_categories' => false,
'manage_options' => true, // Most plugins and pages check for manage_options for checking access level to allow access to pages and settings.
);

Just found this solution which i consider really clean to enter wp-admin with a new role:
Add access cap to backend
Add the cap view_admin_dashboard & read to your new role.
Show the admin bar
Add this function to your wordpress.
# functions.php
add_filter( 'show_admin_bar', function () {
if ( current_user_can( 'view_admin_dashboard' ) )
return true;
return false;
}, 10);
