I followed the instructions to setup but when I go to https://domain.com/blog/install/index.php, the page displays ok and fill out the required information and hit "update config file", my browser then says "this is a non-secure form......", I hit ok and the page just refreshes and I cannot move forward. I've tried PHP version 7.4 / 8.0 / 8.1 and nothing changes apart from if I use PHP 8.0 or 8.1 I get Deprecated errors.
