I think this error is because you are trying to run WebPA 3 (which was updated for PHP 7) with PHP 5.4. The latter does not support the passing of method return values into functions like empty. I would recommend that you do not use WebPA 3 with any version of PHP less than 7; you never know how many incompatibilities there might be. Better to update to PHP 7 instead.
