PHP warning - Use of undefined constant ‘FORCE_SSL_LOGIN’ ‘FORCE_SSL_ADMIN’ on wp-config.php

Question

I have a bothering PHP warning for ages, and I am wondering if someone has solution to this. The following two-line warning is constantly recording in my error_log file:

PHP Warning:  Use of undefined constant ‘FORCE_SSL_LOGIN’ - assumed '‘FORCE_SSL_LOGIN’' (this will throw an Error in a future version of PHP) in /home/myuser/public_html/wp-config.php on line 92

PHP Warning:  Use of undefined constant ‘FORCE_SSL_ADMIN’ - assumed '‘FORCE_SSL_ADMIN’' (this will throw an Error in a future version of PHP) in /home/myuser/public_html/wp-config.php on line 93

In wp-config.php I have the following for line 92 and 93 lines:

define(‘FORCE_SSL_LOGIN’, true);
define(‘FORCE_SSL_ADMIN’, true);

line 91 is empty and line 90 is define('WP_DEBUG', false);

More information: My php version: 7.4.16; Webserver: LiteSpeed; cURL Version: 7.74.0 OpenSSL/1.1.1k.

I have this warning more than a year or two years and with different versions of phps

I am using the plug-in Really Simple SSL on my website as well and everything is fine with that. I also use All-in-one security and firewall on my websites.

Deactivating of plug-ins didn’t help. Any solution to this?

Answer 1

Edit wp-config file :

define('FORCE_SSL_LOGIN', true);
define('FORCE_SSL_ADMIN', true);

just copy this and paste in wp-config file.
