I've built a Drupal 8.6.4 website within Acquia Dev Desktop, but moved it into a local Docker/Docksal setup to continue working (haven't used it before) - on a mac, if it matters. Everything seems fine, but for two issues. The first is a bunch of Security warnings in the logs about htaccess, saying to add an htaccess containing some specific code to the "/var/www/config/default" directory, but I don't have this file directory. It's a Docksal set-up: just ~/projects/projectname/docroot set-up on my computer.
The second issue, which I suspect may be related, is that I can't Drush archive-backup --destination=x/x/x.. It always tells me the file permission prevents it, Even if I give full read/write permission on the folder. But I can do it without the --destination added. It just puts it in a temp folder.
Here's the Error I see - it generates most any time I load an admin page.
Security warning: Couldn't write .htaccess file. Please create a .htaccess file in your /var/www/config/default directory which contains the following lines: # Deny all requests from Apache 2.4+. <IfModule mod_authz_core.c> Require all denied </IfModule> # Deny all requests from Apache 2.0-2.2. <IfModule !mod_authz_core.c> Deny from all </IfModule> # Turn off all options we don't need.
