Hi here's my situation.
I manually installed wordpress for my primary domain to my root directory so now my root have folders like /wp-content and /wp-admin. I was able to do this by visiting domain.com/wp-admin/install.php
I've added a second domain which is an alias to the primary domain. I've also created a folder in the root directory for it so the root has this folder /folder in it. I've uploaded all the files to that folder, but have no clue how to run the installer. I tried visiting domain.com/folder/wp-admin/install.php but nothing happened. What am I doing wrong or which url should I visit to run the installer? Thank you!
