Just want to let you know that I found a serious bug in this mod. The insert statement in database.php to insert the logs info into qlog table will cause serious bug with your checkout_process.php page.
The checkout_process.php page when trying to get the new insert_id of the order submited will get the insert_id from this qlog table instead from the orders table. Please double check your checkout_process.php file. I got customer submitted order and no order has been created because of the mismatch order id causing by this mod.
