Force SSL in WordPress wp-config.php

gistfile1.txt

Just add this to wp-config.php at the top if changing URLs in Settings > General from http to https breaks website:

 // REWRITE TO FORCE HTTPS TO WORK:
 if ($_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https')
   $_SERVER['HTTPS']='on';


I used this on 5/28/25 and it worked perfectly.


I got it from this answer here from 2015 and it still works fine in 2025:

"i used this one. which is fine to go on.

if ($_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https')
   $_SERVER['HTTPS']='on';

if your server port is differed from 443. you can specify it . Otherwise, no need to use it once again ."
