File login php mengarahkan saya ke folder pengguna di xampp tetapi tidak di cpanel

Skrip login saya ketika menggunakan xampp sebagai server mengarahkan saya ke folder pengguna setelah login berhasil, tetapi ketika saya mengunggah ke cpanel, skrip tersebut hanya memuat ulang dan tidak mengarahkan ulang. Tetapi ketika saya mengetikkan folder pengguna setelah nama domain, itu menunjukkan bahwa pengguna sudah login. Seperti www.goo.com/users, file indeks pengguna akan dimasukkan sebagai login berhasil. Apa yang dapat saya lakukan untuk pengalihan yang tepat.
