Does anyone know how to modify this PHP program? It was available free online and I don't know or can't find who was the original owner or programmer. It stops working after I upgraded the PHP program on my website. If anyone can help can you please download this program from here: https://www.idrive.com/idrive/sh/sh?k=j4y9t7o2p1 I have a Christian website that my brother and I created to spread the Words of God to Thailand, Laos, and Vietnam. Before it stop working, we used this program to allow people to download free music for worship, sermons from pastors, and testimony. Please help if anyone of you know how to write PHP.
