PHP Fatal error (TypeError) on PHP 8

Hello Ultimate Member team,

We’re getting a fatal error on PHP 8 caused by an unsupported operand operation (string – int) in your cron class:

[20-Sep-2025 09:09:53 UTC] PHP Fatal error: Uncaught TypeError: Unsupported operand types: string - int in /home/…/wp-content/plugins/ultimate-member/includes/core/class-cron.php:83

The problematic lines are in weekly_events():

$sunday_start = wp_date('w');
$week_start = $sunday_start - absint( get_option('start_of_week') );

wp_date() returns a string, so the subtraction triggers a TypeError under PHP 8.

Environment: WordPress + Ultimate Member (plugin) on PHP 8.x.

Please let me know when a fix will be available or if you need further logs/versions.

Thanks,
Meysam / configwp.ir
