What potential issues could arise when trying to access a specific PHP file after successful login?

One potential issue that could arise when trying to access a specific PHP file after successful login is that the user may not have the necessary permissions to view that file. To solve this issue, you can implement a check within the specific PHP file to verify if the user is logged in and has the appropriate permissions before allowing access. 

<?php
session_start();

// Check if user is logged in
if(!isset($_SESSION['logged_in']) || $_SESSION['logged_in'] !== true) {
    header("Location: login.php");
    exit;
}

// Check if user has appropriate permissions
if($_SESSION['role'] !== 'admin') {
    echo "You do not have permission to access this page.";
    exit;
}

// Your code for the specific PHP file here
?>
