front page is blank

Hi Anusha,

I tried your suggestions:

setting the permalinks to default won’t resolve the problem.
I switched to the default themes twentyfourteen/twentyfifteen and back, the frontpage is still blank.
I renamed the theme folder via ftp, switched to the default themes and back, the frontpage is still blank.

I am posting the code of the file front-page.php – maybe this will help…

<?php

get_header();

the_post();
$post_id = get_the_id();
