posts not posting on homepage properly 404 error

Hello,

I am trying to publish my posts but the post on homepage shows only half a sentence and the image area is shadowed out and does not show up. (I chose in customization page to use home page for posts.

My site is https://www.blisfullymanicmotherhood.com ( I removed all post and further trials and trashed them as it looked really bad.)

When I click on the missing image when it is set to public to read full post it comes up 404 page not found.

I would like for the excerpt to be wrapped around the image (not half a sentence above).

Why is it not finding my page? When I view in preview before publishing the full post looks fine. Then I publish and I get the mess mentioned above.

Why is it only posting half a sentence and hiding image? Then missing altogether when I publish it? Please help me sort this out so I can start posting.

Thank you
Manic Momma
