Despite all of our work to eliminate bugs, some will sneak by us. Exceptions, also known as errors, can occur as a result of software bugs or when blocks and pages are misconfigured. While you can set these errors to be emailed to you (see Admin Tools > Settings > Global Attributes > Email Exceptions List), you can also view the history of these errors here. Exceptions are sorted chronologically. Instead of showing you every error in a large list, we've grouped them by type. This helps you determine how often an error is occurring.
