<h4>Newsfeed likeTheReply Fix</h4><ul><li><strong>Fixed:</strong> JSON parse error when liking a reply — likeTheReply() accessed $reply["acctid_fk"] and $reply["newsfeedidkey_fk"] without null check. When reply doesnt exist (deleted or invalid ID), getNewsfeedReplyByID returns null. Added $reply null guard to the notification block condition.</li></ul>
