I\'ve been running Vagrant successfully for about a week. Last night I ran vagrant reload and now I can no longer access my sites.
I had the same problem when changing the DocumentRoot.
Since you've changed your DocumentRoot to "/any/path/foo/bar", make sure you have the permissions set on "apache2.conf" for this path.
Search for:
in apache2.conf
And add a new block like this:
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
And my guess is that everything is gonna be fine!
