I’ve done a base install of Drupal 8.6.9 on IIS 10 with PHP 7.3.2 and MYSQL 5.7 (IIS rewrite module also). It worked fine. The following day I decided to upgrade patch to 8.6.10 following the usual instructions of deleting everything but your “sites” folder and copying in the new patch files. I then proceeded to run http://localhost/drupal/update.php. The first update page displays fine. Once I click continue I get a 404, page not found, for http://localhost/drupal/update.php/selection.
Any help with this would be greatly appreciated. Thanks in advance !
