 * This happens with PHP 8 when checking out:
    `<b>Fatal error</b>: Uncaught Error:
   round(): Argument #1 ($num) must be of type int|float, string given<br>in <b>/
   home/____/public_html/wp-content/plugins/woo-discount-rules/v2/App/Controllers/
   ManageDiscount.php</b> on line <b>2082</b>`
 * This is a serious issue, as PHP 7 is no longer supported: [https://www.php.net/supported-versions.php](https://www.php.net/supported-versions.php)

 * Hi,
    Thank you for reaching out.
 * The error may occurs due to using of latest core (2.5+ version) plugin and lower
   version of pro (2.4.5 or lower versions).
 * The mentioned error is fixed in our latest PRO pack.
    Our recent version is 2.5.2
 * Can you update both core and PRO pack to recent versions and have a check ?
    
   Something like: [https://nimb.ws/42T8mC](https://nimb.ws/42T8mC)
