PHP Warnings in WP Debug Log. Version

I am receiving the message: PHP Warning: Constant WP_FAIL2BAN_BLOCK_USER_ENUMERATION already defined in wp-config.php

and PHP Warning: Constant WP_FAIL2BAN_BLOCKED_USERS already defined in wp-config.php.

From what I understand, they need to be defined n wp-config.php.

That’s usually caused by defining them too late in wp-config.php - they need to be before the line that says:

/* That's all, stop editing! Happy publishing. */

Let me know if it helps - there are other things to look at if that isn’t the problem.
