I have a new Drupal 8.0.4 site running on Nginx, and I just noticed that the paths for anonymous users have a superfluous
index.php in front of them.
So instead of
I get the following when not logged in
I'm not entirely sure if it was this way since I started building the site, because I was usually logged in I might not have noticed it. But it could also have happened only since I upgraded Drupal core to the latest minor version.
My Nginx configuration is based on the official Nginx recipe for Drupal, with some small differences in the php-fpm configuration for PHP 7.
As mentioned in the comment by Sachbearbeiter, this seems to be an intermittent issue. I don't see it anymore now on my site, some days later.
Any idea what is causing the index.php to be inserted and how I can get rid of it at all times?
