Drupal 8.x

I am using drupal 8, I created Recent content block for the sidebar, It's showing both the recent pages and articles, how can I make it show only the latest articles? I tried the block configuration to restrict the basic pages, but The sidebar disappeared completely. 

Thanks

How do I create a separate menu bar for the logged in user according to their role. I am using drupal 8.

Thanks

Can you help please, I searched for this on google but I can't find a solution, How can I remove the drupal 8 favicon, i tried the theme sitting and global sitting but it's not changing anything because I have to put another link if I want to replace it with my own, But I don't want to replace it I want to remove it.

Thanks

Hi everybody,

I'm using Drupal 8.4 on PHP 7.0.

I've a very strange error and I can't find the reason, can you help me ?

I've recreated a view with a block (old view has been deleted). When  I go to block layout, and try placing my block on a region, I've got an error HTTP 403.

I can't find any other errors, so I didn't understand why I'm getting this error code.

If you have some suggestion...

Many thanks !

I hope that someone can help otherwise some months work has to be re-done

Firstly - me - I am not a professional but have been developing with drupal for some years as a volunteer

I developed the start of a fairly complicated site using Varbase and thought that I had backed up everything prior to updating from Varbase 8.x.4.09 to Varbase8.x.4.10. The upgrade failed and I posted this under another question and also on the Varbase distribution. So far no action.

So there are two questions

    $path = '/node/YOURNID';
    $alias = \Drupal::service('path.alias_manager')->getAliasByPath($path);
    $response = new RedirectResponse($alias);
    $response->send();
    return;
