Debug Mode
The Debug Mode is useful if you're developing a website / application with pimcore.
With debug-mode on, errors and warnings are displayed directly in the browser, otherwise they are deactivated and the error-controller is active (Error Page).
If you are using Pimcore_Mail to send emails and the Debug Mode is enabled, all emails will be sent to the debug email receivers defined in "Settings" -> "System" -> "Email Settings" -> "Debug email addresses". In addition a debug information is attached to the email which shows you to who the email would be sent if the debug mode is disabled.
DEV-Mode
The development mode enables some debugging features. This is useful if your're developing on the core of pimcore or when creating a plugin.
What exactly does the dev mode:
- Loading the source javascript files (uncompressed & commented)
- Disables some caches (Webservice Cache, ...)
- ... and some more little things
