I am sorry to write a new post here, as I have already found that others have had some similar problems with upgrading from a Drupal 6 page that uses image assist tags for showing images. However, I have not been able to solve the problem, I so would be very thankful if anyone could please explain how I should make this work.
The upside: I have managed to migrate everything important, so apart from none of the pictures shown with image assist on the old site, everything else works great.
I want to make the 'subject' field on my contact form optional, or ideally remove it completely. I have found documentation for this on Drupal 6.9 https://www.drupal.org/node/724130, but I can't find anything for Drupal 8.
Any ideas how to make this happen, assuming it's possible.
I'm traying to install drupal buy command line with : drush site-install standard --account-name=username --account-pass=password --db-url=mysql://root:root@localhost/drupal_test
