I have this problem from the first time I have updated my Moodle 2.3 to 2.5:
Warning: set_time_limit() [function.set-time-limit]: Cannot set time limit in safe mode in /home/elgst/public_html/turismo/mod/game/cross/cross_class.php on line 138
Any easy way to solve it?
Thanks in advanced.
you should open an issue in https://tracker.moodle.org/browse/CONTRIB/component/10295 to ask the mantainer if it is possible to avoid that call.
Otherwise the solution is to ask your administrator/hosting provider to unset the PHP safe mode for your Moodle installation.
