PHP脚本返回500内部服务器错误

Question

I get 500 error for PHP scripts, but HTML files are served without a problem.

Here are my configs:

httpd.conf

    <VirtualHost 127.0.0.1:8080>
    ServerName example.com
    DocumentRoot /var/www/example/data/www/example.com
    ServerAdmin [e-mail]
    AddDefaultCharset off
    SuexecUserGroup root root
    CustomLog /var/www/httpd-logs/example.com.access.log combined
    ErrorLog /var/www/httpd-logs/example.com.error.log
    <FilesMatch "\.ph(p[3-5]?|tml)$">
        SetHandler application/x-httpd-php5
    </FilesMatch>
    SetEnvIf X-Forwarded-Proto https HTTPS=on
    ScriptAlias /php-bin/ /var/www/php-bin-isp-php56/example/

    </VirtualHost>
    <Directory /var/www/example/data/www/example.com>
        Options +ExecCGI
    </Directory>
