I know this must have been asked a lot, and thank you so much for taking your time in answering this. :]
I have WordPress installed in the root folder of my domain.
Now I want to install another one into a subdirectory labeled shop that I will later redirect to shop.mywesite.com.
I've set everything up, but when I try to access the install.php, there's a 404 Error.
How do I fix this?
