I guess you have edited a php file that belongs to ispconfig and removed the < at the beginning of the first line or the installation got interrupted, as the above problem is a sourcecode error which is not present in the released 3.0.3.2 stable files.
I dont know which files you edited. You sould start with the file /usr/local/ispconfig/server/cron_daily.php and if the problem is not there, check the files that are included into that file.
