URGENT: Fix PHP Deprecated Function

My debug log is inflated in size and 90% of the issues in this log shows this warning message

[20-Nov-2025 02:57:46 UTC] PHP Deprecated: preg_match(): Passing null to parameter #2 ($subject) of type string is deprecated in wp-content/plugins/woocommerce-boost-sales/includes/mobile_detect.php on line 1155

My debug file went from 100MB to 8.52GB in just 1.5 weeks.

Please update this plugin and all your other woocommerce plugins (if applicable) so remove this warning message.

I dont want to be removing my debug file every 1.5 weeks as that would be a pain!
