Hi, I wanted to have a subdomain to link to where I installed the website but when ever I tried to do it, it always redirect to the main site.
For example, if a is the website I installed,

This is what happened:
a.domain.com -->domain.com

I wanted this to happen:
a.domain.com -->domain.com/a

I did it with different website creators and it works but for some reason, this one doesn't.
Please tell me what I should do, I am not very familiar with these kinds of stuff.
Thank You
