I've upgraded my osticket v1.10 (stable) installation to PHP 7 and it causes this warnings:
PHP Warning: Declaration of AssignmentForm::render($options) should be compatible with Form::render($staff = true, $title = false, $options = Array) in /include/class.forms.php on line 4150
PHP Warning: Declaration of TransferForm::render($options) should be compatible with Form::render($staff = true, $title = false, $options = Array) in /include/class.forms.php on line 4270
I though v1.10 was supposed to be PHP 7 compatible (?).
