In Drupal front-end, menu drop-down hierarchy not displaying - drupal

The Drupal webiste I'm working on: http://student17.cas181s.com/project
I have a menu dropdown, with menu items that have children, I've already check-boxed the "show as expanded" for literally all my menu items. Visitors viewing my front-end cannot see this (only I can see this, in back-end, as admin). Why is this? I'm using Bartik 7.34 theme.

Check out privilages for anonymous user for that content that your friends cant see. In drupal if someone can't see page content he won't see link to that page also. Maku sure that pages are published - admin can see all the content but most of the user groups only published one. At end...clear the cache.

WordPress: Not displaying changes of updated pages

I have update a page in my wordpress site using web admin back end, but what I see is that even if I update a page, it does not get updated online. Moreover, some of the content of the page which I see online /live are not actually texted in the area where we put the content.
On the right side navigator, in the page attribute area Parent has been set to No Parent, template --> Home Page.
Can you please let me know what could be the possible reason why the live content of the page is different from what I can see in the actual text area through web admin panel?
Also updating a page does not reflects on the page as well for that particular page.
First make sure you are editing the right page. Click in the frontend adminbar on edit instead of navigating in the backend through the pages list.
Secondly it can be any caching related issue. Check out if there are any plugins or settings for this.
Areas that are on the page but not editable via the content can be widgets or any kind of theme builder stuff. Check in the backend design->widgets.
The page hierarchy (parent: no parent) can be differ from the actually website navigation. Check out design->menus. It is possible to build other hierarchies in the menus.

Drupal 7 - Node Gallery visible for logged users only

I have Drupal 7 with NodeGallery installed. I have several galleries in on my website.
Some of those galleries are linked to the main menu items and always visible and some of those are linked to menu items visible only after the user has signed up.
But when someone is logged-in and for example sends a link to gallery (like http://my.site.com/?q=node/1477), that is hidden for external (unlogged) users, they see that gallery, although they don't see it in main menu.
The option in Content management (for this gallery) "Is private" and the combo box "Authenticated only" has no effect (has effect only with the visibility of the link in main menu). If someone knows the link, he has access to the gallery. That is not desirable.
How can the permissions of view of the concrete gallery be restricted to only authenticated user?
For controlling the logged in and logged out menu items you can use menu item visibility module URL: https://www.drupal.org/project/menu_item_visibility where you can control which menu item is visible to which role.
And you can use hook_node_view hook to check which node(s) to be visible to which roles of user or you can use nodeaccess module to have a backend to make your node visible to which user URL: https://www.drupal.org/project/nodeaccess

menu_navigation_links drupal is not returning the menu tree

I have created a custom menu in Drupal 6.3 and when I accessed the menu using the menu_navigation_links it is returning the result only for the home page but for other pages it is returning the empty.
You must publish content if you want it to be visible in menu. That goes even for back-end, which is really strange. Also check on access rights. Is that hidden content accessible to user role you are using.

Customizing the Blocks admin page

I am looking for a way to limit a specific user role (blog admin) on our Drupal site to administering blocks on the main site theme only, and not the admin theme.
Currently, when this user goes to the blocks admin page, they see two theme tabs in the top right. Is there any way to hide this tabbed menu? I'm working with end users who may be confused seeing these two theme menu tabs.
thanks,
Evan

Drupal 7 admin new menu

Is it possible to implement a new admin menu in Drupal 7?
Currently I am using Seven theme.
What I want to do is adding another tab on the Content menu with just: Comment, Comment to content, Comment, Submission.
I added a new menu on the admin menu structure, but the menu is not showing anywhere.
I made page--admin--content--submission.tpl.php to start making the interface, but I can't make it according to the current selected admin theme.
Please point me somewhere since I already googled with no luck.
Update screenshot :
Did you try clearing your cache? You can do that via the Performance page, at yoursite.com/admin/config/development/performance.
