Serious errors, such as the inability to open/connect to a Class, are recorded in the Log, accessible through the Log page.

Also, to assist in debugging when developing remotely, it is possible to turn on Logging for a particular User; thereafter, a log file of the output of the most recent server side processing for that user will be maintained, and is accessible through the Log page.

The log should be checked periodically by a system administrator, to confirm that no errors are occurring and being recorded, that are going unnoticed or unreported by users.
