I made some migration of pretty old website to d8. And urls ported fine from latest WP version:
/user1/article-name1 /user2/2009/article-about-something /user3/2017/11/06/article-something
But from what I see in google many articles would be linked with index.php at the end i.e.:
/user1/article-name1/index.php /user2/2009/article-about-something/index.php /user3/2017/11/06/article-something/index.php
etc etc. Somehow WP could handle it (no traces of overrides in htaccess), but Drupal would not.
Puzzled how to fix it with htaccess, preferably with 301 redirect.
Thanks for your ideas!
