friendica-poller

<b0r7> hi, i need some help: i tried testing the cronjob which should execute include/poller.php
[08:55] <b0r7> so i did su www-data
[08:56] <b0r7> and /usr/bin/php include/poller.php
[08:56] <b0r7> owner of all friendica files is www-data
[08:57] <b0r7> however .. the console stays dark.. no ouput and no processing whatsoever..
[08:57] *** cunrad44 quit (Ping timeout: 272 seconds)
[08:58] <b0r7> the server rund ubuntu and as far as i understand it shoul work but im obviously missing something. i can log into friendica and everythings working fine except the cron
[08:59] <b0r7> i would be most gratefull for any pointers.. well as i am writing i realise i should look for a log file of php
[09:05] <b0r7> well:
