What are some common issues with PHP forums that result in constant page reloading or "page cannot be displayed" errors?

Common issues with PHP forums that result in constant page reloading or "page cannot be displayed" errors can be caused by incorrect server configurations, database connection problems, or inefficient code that leads to excessive server resource consumption. To solve these issues, ensure that the server configurations are correct, the database connection is established properly, and optimize the PHP code to reduce resource usage. 

// Example code snippet to optimize database connection in PHP
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "forum";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
