I created my skin following the instructions in another post and then added the filter to functions.php on my theme.
I used this post as reference.
The problem is I can see the preview of my skin but not in the page.
In fact, the skins never worked, I changed the skin but I always got the same skin.
This is the page where I’m trying to use PUT

the password is “put”
Thank you.
