Posts will not display on homepage, the usual fixes havent worked…

Hi all,

I am designing a wordpress site for my sister and have hit a snag…

Only on the homepage (index.html), I cannot get any posts to display on the homepage. I get the “Not Found. Sorry but you are looking for something that isn’t here” error.

I have deleted the “Hello World” post. However, I have read a bunch of posts by other users to just “make another post” and this will clear up. I have made an initial blog entry but it still wont show up on my homepage. However the entry does show up in the “uncategorized category” where we put it

Other things I have also tried:

Using different themes…

Disabling all plug-ins…

Clearing my browsers cache…

My sister is hosting the wordpress page with an outside hosting company called FatCow. Not sure if that could be causing the issue? Or if there is a problem with my index.php coding page?

I do know a decent amount of html/css but php is a work in process…

Website is https://www.goalsetentertainment.com

And here is the index.php code…
