Hi there;
Not sure what is happening, but I am getting a Critical error from Xstore core on my site. I had to deactivate it.
This is the message it is giving me: An error of type E_COMPILE_ERROR was caused in line 16 of the file /home/e7qaii3xesj0/public_html/wp-content/plugins/et-core-plugin/packages/xstore-waitlist/emails/class-customer-notify-new-request.php. Error message: Access level to XStoreCore\Modules\WooCommerce\XStore_Waitlist_Customer_Notify_New_Request::$placeholders must be public (as in class WC_Email)
