Drupal 8.x

I want to add several special metatags to the head section of my pages. Specifically, I want to add Google, Bing, Yahoo, DuckDuckGo validation codes. I have metatags 8.x-1.0 beta7 installed on the site. Can this module be used to accomplish this?

I uploaded a D8 site several days ago and today I searched Google and DuckDuckGo for the domain name and each search engine returned the same troubling reply:

Google: A description for this result is not available because of this site's robots.txt
DDG: We would like to show you a description here but the site won't allow us.

• The URL alias field needs to be uninstalled.

Taxonomy term

• The URL alias field needs to be uninstalled.

I got this warning at "Status report" page, anyone have idea how to fix it?

I've looked for an answer to this specific question, but I'm not finding it.

I have an account on Bluehost, which has Wordpress installed on it. I need to keep this Wordpress site, and install Drupal in a subdomain - hopefully.

I don't know if this is possible, or feasible. I have created the subdomain, and can access the folder it created for it (the subdomain is apsis.samplesite.com, and there is an /apsis folder on the server. )

I'll probably just end up asking Bluehost support how to do this, but if anyone has any ideas, I'd be glad to hear them.

I currently have a page set up where users are able to submit abstracts in pdf or txt form. Currently, those files go to /my/drupal/path/sites/default/files/2016-05. I would like to set this directory to perhaps .../files/uploads and have a cron job that pulls and deletes files from it. Is there a way to set this or a better way to do it in D8?

Hi there,
today I ran into problem. After I updated to Version 8.1.1 the hook_views_query_alter() was not called anymore
