Cannot upload new photos to file manager.

Getting the following message every time I try to upload a new photo

Upload Failed


Declaration of Carbon\Carbon::setTime($hour, $minute, $second = 0) should be compatible with DateTime::setTime($hour, $minute, $second = NULL, $microseconds = NULL)

Any idea as to how I can solve the problem?
