Error on Install

[magnum61]

Hi,

just tried to install FlightAirMap on my Raspberry. Apache2 is installed, but the install routine cannot be opened. It shows this in the error logs of the webserver:

AH01071: Got error 'PHP message: PHP Fatal error: Unparenthesized a ? b : c ? d : eis not supported. Use either(a ? b : c) ? d : eora ? b : (c ? d : e) in /var/www/html/flightairmap/require/class.Common.php on line 759'

I am not gode in coding, so any support would be appreciated
