Drupal 8.x

Hi, i am a noob developer from Turkey and learning Drupal 8. I search everywhere but couldn't find. I am tring to keep track of language choise of anonimous users and store this choise in the cookie but i stucked on drupal cache. Next time when user comes to my site again i want to redirct user to appropriate url. Could you direct me to correct documantation or help me?

Hi,

I ran the standard updates via Drush, but one of the scripts ran out of memory.

Now I cannot list content.  The rest of the site still works.

Output from the drush up :

I believe there is a new feature in D8 letting us create collapsible blocks (see screen capture). But I couldn't find any documentation about it. Can someone explain please.

Who are the best hosting providers for Drupal 8 that guarantee as close to 100% uptime as possible? 

I am familiar with Acquia but would be interested if others have had positive experiences with other Drupal 8 hosts. 

I'm particularly interested in enterprise level service with strong support and/or data centres located in Australia.

When searching my Drupal site In Internet Explorer 11 with Mayo as the default theme, the Advanced Search form appears before the search results, so you must scroll down to see the results.  In Chrome, the Advanced Search form is above the search results, but it is hidden.  You must click a down arrow to make the advanced form appear.  In IE 11, there is no down arrow.  Is there any way to fix this so that the Advanced Search is hidden in IE(without disabling the advanced search)?

The search does work correctly in IE with the Bartik theme.
