Declaration of case-insensitive constants is deprecated

Hi,

I’m getting notification in my debug.log because deprecated declaration in one of the PHP functions.

PHP Deprecated: define(): Declaration of case-insensitive constants is deprecated in /var/www/rekrytointi.com/public_html/wp-content/plugins/registered-user-sync-activecampaign/rus-activecampaign.php on line 15

Luckily the fix is easy and you only need to modify single line in file “rus-activecampaign.php”.

Here is the old line(15):
define( 'RUSAC_URI', plugin_dir_url( __FILE__ ), true );

Here is the new line(15):
define( 'RUSAC_URI', plugin_dir_url( __FILE__ ) );

Here is link for the PHP function where you can see that the third declaration(“case_insensitive”) is deprecated since PHP 7.3.0 :

Thank you for your time
Sincerely
