Cookie Child Theme HELP!

My first time posting here so I don’t even know if this is the right place. I have the Cookie Child Theme and find the back office so confusing. I’ve just gone into the posts and see that there now appears to be no option to view without HTML coding. Is this correct? I am no familiar with HTML and so seeing all of that amongst my text does my head in. Please help direct me. Many thanks in advance.

Please get in touch with the theme author here:

Or via item comments page:

Thank you
