How can I prevent the system files from getting corrupted when adding and removing virtual sites and users?
The most common source of corrupted configuration files is due to someone using the “back” button or their “stop” button on their browser when making changes to users or sites. The solution is to let any operation that was started complete fully, even if it was a mistake. If you make a mistake, you can always correct it after the first operation has completed fully just by saving the corrected changes.
