Static posts page is not working

When you use “static front page” are you selecting the actual page you want displayed on the home page?

It sounds like you want the “Splash” page as the home page. You should create the Splash page in the Page Edit Screen, select a custom page template if that is what you’re wanting to use and save the page. Now you’ll go to Reading>Front Page Displays *Static Page and choose the Splash page from the drop-down list. Your front page should then display the Splash Page.

Then you would select the blank page Blog in the drop-down list next to the Latest Posts option.
