want second site to be a copy (theme,colors,fonts etc) of the original.

working on 2 sites. I have the original https://fortwaynespeaks.com that I have made changes to. I created a subdomain https://blog.fortwaynespeaks.com. The main site is for podcasts but we want a separate written blog to be available separate from the podcast posts. I did the multisite thing so that the posts wouldn’t be mixed together.

I want the blog site to be exactly the same as the original but can’t figure out what I need to do to make that happen. The difference is that it would house only the written blog.

Also, when I search for blog.fortwaynespeaks.com it comes up as a default wordpress theme with sample content. When I go into the wordpress dashboard to “visit the site” the “Trim” theme comes up but it doesn’t have the changes or content. What am I missing? Thanks for your help.
