ChurchCRM Application Platform Prerequisites

Charles edited this page Oct 18, 2018 · 2 revisions

ChurchCRM has a few platform prerequisites, and a built-in mechanism to ensure that all prerequisites are met. If there are any unmet prerequisites, a message will be displayed during setup and a notification will be displayed during run time.

Prerequisites are validated at every page load, so if the hosting environment is changed to an incomplete / unsupported model, a notification will appear
