Internal Server Error after clean install OC10.0.2

Here is my log entry:{"reqId":"WULdXdopfO1t7eKM8FikLAAAAAY","level":3,"time":"2017-06-15T19:17:49+00:00","remoteAddr":"","user":"--","app":"PHP","method":"GET","url":"\/status.php","message":"You are using a fallback implementation of the intl extension. Installing the native one is highly recommended instead. at \/home\/cloud\/public_html\/lib\/composer\/patchwork\/utf8\/src\/Patchwork\/Utf8\/Bootup\/intl.php#18"}

Using CentOS 7, PHP 7.0.19, OC 10.0.2

I switched back to OC 9 and PHP 5.6 and it is working fine.
