Changing Page Content

I am new to wordpress and I can’t seem to figure out how to change the generic content on the theme I have activated.

I chose Webalizer. I can add blog posts and they show up on the template. I can customize colors for the background.

I have created pages but I can see them on the site either. How can I get them to show up on the site?

Also, I cannot find where to change/remove the title on the site that says “Webalizer” in the top left corner, nor can I change any of the content on the page.
