Home page doesn’t load up

Hi

I recently uploaded to 2.3, and updated a few things on my home page, with is hosted by Yahoo

Now when i type in my url https://www.nonhlanhla.com, it doesn’t take me to my home page., rather to the index.php page, wich is blank, unless i type https://www.nonhlanhla.com/index.html

I am new at all this, and a bit confused as to what might have gone wrong
