What common error message might occur when using the Sitecake miniCMS with PHP?

When using the Sitecake miniCMS with PHP, a common error message that might occur is "Sitecake requires PHP 5.3 or higher". This error typically happens when the server running the PHP script has a version of PHP that is lower than 5.3. To solve this issue, you will need to update the PHP version on your server to 5.3 or higher.

// Check if PHP version is at least 5.3
if (version_compare(PHP_VERSION, '5.3.0') < 0) {
    echo "Sitecake requires PHP 5.3 or higher. Please update your PHP version.";
    exit;
}
