wp_template_uri debug

Hi there,

I’m having trouble with one website I was working on.
It was developed on a subdomain, like: subdomain.mydomain.com, and then it’s transferred to livedomain.com

Problem is that get_stylesheet_directory_uri() function, and all other similar functions are returning subdomain.mydomain.com as result.

I have changed, site_url / blog_url, but I’m struggling to find out how this function is determinating url.
I have tried to search trough core files but not much luck.
Also, I have checked PHP/$_SERVER details, they are all showing correct domain.

Any help would be useful.
