The latest #develop code reports a problem started by poller.php:

PHP Warning: Invalid argument supplied for foreach() in /home/.../public_html/friendica/include/poller.php on line 208
PHP Stack trace:
PHP 1. {main}() /home/.../public_html/friendica/include/poller.php:0
PHP 2. poller_run() /home/.../public_html/friendica/include/poller.php:265
PHP 3. poller_kill_stale_workers() /home/.../public_html/friendica/include/poller.php:58

Maybe again some better variable tests? And I saw a message this #friendica installation is having problems, several hits on F5 (reload) key brought it back again.
