Links on site adding index.php in URL I have a Drupal 8 site and am encountering an issue. When I visit the site as an anonymous user and click a link on the menu, it adds /index.php to the url. Then if I navigate to that page and click another link in adds another index.php (i.e. example.com/index.php/index.php/link1/link2) and therefore the page will not load. This does not happen if I am logged into the site, has anyone encountered this before? I tried a fresh htaccess file and beyond that I am stumped. It is on a shared hosting plan. Any help is appreciated.
I had the same problem.

I have a view with links to content, where the URLs are item/[one content's field value]. One day, I watched the view as anonymous user and noticed that these had been changed to index.php/index.php/item/[one content's field value]. (On the other hand, when I visited as administrator user, it didn't happen.)

I didn't know why it happened, and it was solved by executing drush cc render.

However, the problem would still be left.

The environment is Drupal 8.3.9 and PHP 7.0.25.
