mpdf.php removed from server
so my web is using Mpdf to download some document in PDF. I installed it using composer in my local server, then upload all the files the library needed to hosting server. But whenever I try to use it, it always disappeared. File is missing. I try to upload it again, it's uploaded. But when my code called it, it gone missing again. Don't know what happen here, but it's working fine in my local server. Help?
