Header Question

I’m sorry but as you are using a commercial theme, you need to seek support from the theme’s vendors.

Oh, okay. This never happened to me before when I posted here. Is this something new?

No. We have never been able to access commercial themes.

strange, as I have gotten help here dozens of times. Also, I did not know mine theme was commercial, as I believe I downloaded on the word press site some years ago.

I seriously doubt that.

Theme Name: Medica
Theme URI: https://themefuse.com/demo/wp/medica/

My blog is at:

Sorry, I placed the wrong link here.

The other link is to my home page, which is html, not word press.

Again, sorry, as I placed the wrong link.

So, can someone help me with this issue here. I just want to be able to make the header go from 152px to 300px.
