Wordpress redirects issue

**Wordpress loads from a subfolder**

- Domain name : mcs-poland.com
- Hosting OVH perso

Hi Everyone,
I have made a bad setup in the beginning and now I don't know how to fix it. The situation is:

1. The domain points to **./mcs** folder where was a dummy website build on wordpress
2. In a folder **./mcs/hazel-test** I set up another wordpress and started to develop my real website
3. I copied all from **./mcs/hazel-test** to **./mcs** in hope that my domain mcs-poland.com would load the page from **./mcs** folder
4. but in fact accessing the domain cause immediate redirect to **mcs-poland.com/hazel-test** and this is what is visibe as URL.
5. also I cant log-in to a wordpress instance in **./mcs** due to mentioned redirect

How can I fix it, ie. remove redirect and make page load from **./mcs** ?

I do appreciate your help.
