PHP Warning: Undefined constant LOGGED_IN_COOKIE in performance.php (PHP 7.2)

A quick review with the PHP Compatibility Checker plugin yielded several issues that seem straightforward:

Hi,

The LOGGED_IN_COOKIE issue is a known issue, it has been fixed in the latest version, it will release within 1-2 weeks

Regarding the compatibility checker, the mysql is false positive, we are using an own function for some queries: Swift_Performance::mysql_query

Regarding safe mode warning it is legacy stuff, you can ignore it. (it will be removed in 2.0 as the minimum PHP requirement will be PHP 5.6)

Awesome – thank you, and thank you for a great tool!

Hi, so what do I do exactly when I get this warning?

Warning: Use of undefined constant LOGGED_IN_COOKIE – assumed ‘LOGGED_IN_COOKIE’ (this will throw an Error in a future version of PHP)
pluggable.php on line 773

and
Warning: Use of undefined constant SECURE_AUTH_COOKIE – assumed ‘SECURE_AUTH_COOKIE’ (this will throw an Error in a future version of PHP)
user.php on line 357

Thx for the support.
