Tagline, site title header, block removal

You can download a blank child theme from here:

https://docs.generatepress.com/article/using-child-theme/#installing-a-child-theme

But its only required if you intend to create your own functions.php or add your own templates.

Realy appreciate,
I believe I done the right thing, I just installed GP theme and your GP Premium plugin.
I will contact my host to solve the problems occurred, if not done, I will contact you later.
Thanks and regards

You're welcome
