Drupal 8.x

I really don't know what's happened, just launch flush cache and now I got always following message and all the site is out of service!
What can I do????

Hello,
after installing Drupal 8, I run into trouble getting breadcrumbs to work. They show up, but behave strangely. Sometimes, switching to another page/article does not update the breadcrumb. Sometimes, the breadcrum does not reflect how a page/article is embedded in a submenu.
What is the best way to implement breadcrumbs in Drupal 8? I cannot find any tutorials or todo on this.
Thank you!

Hi,

I have a text field used to enter a code (like 1111). This code is linked to a file (image) hosted in another server.
When a user displays this content type, I want to automatically display 3 things :
*the field content with the code (1111 for exemple) (I know how to do it)
* a picture whose url will always be : www.url.com/FIELD_CONTENT.jpg (www.url.com/1111.jpg)
* a link to the picture

Is it possible to do that ?

i have installed zircon_d8 drupal distribution in my website. only layout is visible now. slider,header and footer and our partner link panels are also not working, how to do i solve this problem?

Drupal has its core migrate module.

It need to enable migrate module and run the migration in url example.com/upgrade.

How do I run the url above with drush?

Is it using the drush command drush pm-update drupal to do the migration above?
