After updating lsphp7 to lsphp8 from the OpenLiteSpeed management backend. An error occurred
The problem is that I have three websites, all with the same configuration and the same program
Why is there an error on only one website

Code:
[STDERR] PHP Fatal error: Uncaught TypeError: Unsupported operand types: int / string in /wp-content/plugins/woocommerce/includes/wc-core-functions.php:987
