My site isn't working

Im running 4.4.2 running the promenade theme

Hi, can you give more info? What do you mean with “I can edit it just fine”?
Do you have website link?
Could you try to disable all plug-ins?
Also change to default theme.

In wordpress i can edit the page and publish and view the pages and site. But when i go to the url: https://www.thereisnous.org its just a blank screen.

if i disable all plugings and change to default theme will i loose all my work?

I deactivated the plugins and when i went to the url it said:

Warning: Cannot modify header information – headers already sent by (output started at /home2/geroldvie/public_html/thereisnous.org/index.php:3) in /home2/geroldvie/public_html/thereisnous.org/wp-includes/pluggable.php on line 1228

Hi, you will not loose any work when disabling all plug-ins and activate default WP theme (twentysixteen for example).
It is necessary to troubleshoot the problem.

When, with all plug-ins disabled and default theme the website is accessible then you know more where to look.

did you do updates?

the error message could be a site hack problem.

also, did you changed something at wp-config?
