I was trying to adjust my post settings to the Beaver Builder Theme I have enabled on my WP page to actually fill the entire page and accidentally wiped out the code to my tpl-full-width.php file. Can someone provide me the code to this file? And if anyone knows a easy way to adjust my setting for my posts to fill the entire page like my pages do please let me know.

We are a non-profit and do not have a ton of money for support so any help is much appreciated.

I am getting blank screen when I am browsing the single post details page.

You should be able to get the theme zip from your account area and get a fresh copy of the file from the zip.
