Log Levels
----------
Verify the ``loglevel`` in your ``config.php``. The default the log level is
set to ``2`` (WARN) in new installations. Sometimes this parameter is inadvertently
left at the DEBUG level (``0``) after a troubleshooting event. In some older installations this
parameter may also be something other than the default. Use ``0`` (DEBUG)
when you have a problem to diagnose, and then reset your log level to a
less-verbose level. DEBUG outputs a lot of information, and can affect your
server performance.
Debug Mode
----------
Verify that ``debug`` is ``false`` in your ``config.php``. The default is ``false`` in new
installations (or when not specified). While similar to the DEBUG logging level, this option
also disables various optimizations (to faciliate easier debugging) and generates additional
debug output both at the browser level and server-side. It should not be enabled in production
environments outside of isolated troubleshooting situations.
