No Access but Displays in Menu on the backend

Thank you for pointing this out. This will need a small change.

If you can wait for the next version I will put it in there. Otherwise you can try this:

1. Go to wp-content/plugins/photonic/photonic.php, line 222. You will see this:

   
   function add_admin_menu() {
   	global $photonic_options_manager;
   	$this->options_page_name = add_menu_page('Photonic', 'Photonic', 'edit_posts', 'photonic-options-manager', array(&$photonic_options_manager, 'render_settings_page'), plugins_url('include/images/Photonic-20-gr.png', __FILE__));
   	$this->settings_page = add_submenu_page('photonic-options-manager', esc_html__('Settings', 'photonic'), esc_html__('Settings', 'photonic'), 'edit_theme_options', 'photonic-options-manager', array(&$photonic_options_manager, 'render_settings_page'));
   	$this->getting_started_page = add_submenu_page('photonic-options-manager', 'Getting Started', 'Getting Started', 'edit_posts', 'photonic-getting-started', array(&$photonic_options_manager, 'render_getting_started'));
   	$this->authentication_page = add_submenu_page('photonic-options-manager', 'Authentication', 'Authentication', 'edit_theme_options', 'photonic-auth', array(&$photonic_options_manager, 'render_authentication'));
   	$this->gutenberg_page = add_submenu_page('photonic-options-manager', esc_html__('Prepare for Gutenberg', 'photonic'), '<div style="color: #c66">'.esc_html__('Prepare for Gutenberg', 'photonic').'</div>', 'edit_posts', 'photonic-gutenberg', array(&$photonic_options_manager, 'render_gutenberg'));
   	$this->helper_page = add_submenu_page('photonic-options-manager', 'Helpers', 'Helpers', 'edit_posts', 'photonic-helpers', array(&$photonic_options_manager, 'render_helpers'));
   }
   

2. Replace that whole block with this:

   
   function add_admin_menu() {
   	global $photonic_options_manager;
   	if (current_user_can('edit_theme_options')) {
   		$parent_slug = 'photonic-options-manager';
   	}
   	else if (current_user_can('edit_posts')) {
   		$parent_slug = 'photonic-getting-started';
   	}
   
   	if (!empty($parent_slug)) {
   		$this->options_page_name = add_menu_page('Photonic', 'Photonic', 'edit_posts', $parent_slug, array(&$photonic_options_manager, 'render_settings_page'), plugins_url('include/images/Photonic-20-gr.png', __FILE__));
   		$this->settings_page = add_submenu_page($parent_slug, esc_html__('Settings', 'photonic'), esc_html__('Settings', 'photonic'), 'edit_theme_options', 'photonic-options-manager', array(&$photonic_options_manager, 'render_settings_page'));
   		$this->getting_started_page = add_submenu_page($parent_slug, 'Getting Started', 'Getting Started', 'edit_posts', 'photonic-getting-started', array(&$photonic_options_manager, 'render_getting_started'));
   		$this->authentication_page = add_submenu_page($parent_slug, 'Authentication', 'Authentication', 'edit_theme_options', 'photonic-auth', array(&$photonic_options_manager, 'render_authentication'));
   		$this->gutenberg_page = add_submenu_page($parent_slug, esc_html__('Prepare for Gutenberg', 'photonic'), '<div style="color: #c66">'.esc_html__('Prepare for Gutenberg', 'photonic').'</div>', 'edit_posts', 'photonic-gutenberg', array(&$photonic_options_manager, 'render_gutenberg'));
   		$this->helper_page = add_submenu_page($parent_slug, 'Helpers', 'Helpers', 'edit_posts', 'photonic-helpers', array(&$photonic_options_manager, 'render_helpers'));
   	}
   }
   

Be careful with the above code though … if you make a mistake it can cause you to get locked out.

Thanks for the prompt reply. I may give it a shot with a test site!

I have addressed this in version 2.28.
