It seems php configuration changed with the upgrade. Your old one had
output_buffering turned on in php.ini.

Instead of turning it back on you should fix your app, open
/Library/WebServer/Documents/testit/Logsafe_project/db_fns.php, go to
line 212, something's outputting there something (echo, print, anything
outside <?php ?>), maybe even a whitespace character.
