Scheduled maintenance hasn't run in the past hour. This may mean that you have not set it up correctly.
Automatic maintenance is currently disabled, so when Revive Adserver delivers banners, automatic maintenance will not be triggered. For the best performance, you should set up scheduled maintenance. However, if you are not going to set up scheduled maintenance, then you must enable automatic maintenance to ensure that Revive Adserver works correctly.
