I use Acquia Dev Desktop2 on Mac for php7.0. I think that it is the previous version. I was waiting for the upgrade to use php7.1, but there was no announcement in check for update menu. I have no choice, so I downloaded it and overwrite install. The bad request will be displayed on all local sites. Phpmyadmin of all sites will be displayed correctly. What is the solution?
What I can think of is using underscores for site addresses.
In order to remove the underscore, I edited vhosts.conf and restarted apache. 'But request' was not improved.
