Having Trouble with my First Jekll Site

Hi, I am trying to setup a site on Github Pages using a Jekll template. I have selected a template (flexible-jekll) and forked the repository. Then I have changed the name of the repository to be my githubname.github.io. However I am having an issue…

When i use that second link to get to my website, all of the pretty formatting does not show up, so it is all plain text with no pictures loaded.

Here’s what it looks like and what it should look like:

I would really appreciate help with this issue. Thank you!
