Twins - Corporate Business WordPress Theme

Hello, Really like this theme and would like to purchase. Does it support custom header, can I change the header?

Thanks much!

Hi, How can I remove the “Post A Comment” on each page? I don’t want people to be able to comment.

Thanks.

Also, is there a list of shortcodes somewhere? I’m looking at the documentation but it makes no sense to me. The theme is not very well documented.

I can successfully create a full-width page (no widget space appearing) but I cannot create a full-width post. There’s still empty white-space where the widgets would normally appear. This is really troublesome since I need a full-width post. How can I fix this? Or better yet, can you fix this?
