Warning: wp_initial_constants() [function.wp-initial-constants]: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'America/New_York' for 'EDT/-4.0/DST' instead in /home/tenisc5/public_html/wp-includes/default-constants.php on line 20

Fatal error: Call to undefined function is_multisite() in /home/tenisc5/public_html/wp-includes/default-constants.php on line 20
