It is possible to configure Magento to generate system logs and exception logs upon any error. This is most useful as a way to investigate issues during development, but less practical for live stores for anything other than short-term use.
ATTENTION: Enable the logging feature only for as long as necessary. If left enabled for a prolonged period, these logs will occupy significant disk space and slow down your site.
