Correct OwnCloud errors

Hello, I have hostgator business shared hosting, going to upgrade to their cloud hosting shortly, but I am having errors on a service called owncloud ([login to view URL]). I am getting the following errors: Security & setup warnings This server has no working Internet connection. This means that some of the features like mounting external storage, notifications about updates or installation of third-party apps will not work. Accessing files remotely and sending of notification emails might not work, either. We suggest to enable Internet connection for this server if you want to have all features. cURL is using an outdated NSS version (NSS/3.19.1 Basic ECC). Please update your operating system or features such as installing and updating apps via the app store or Federated Cloud Sharing will not work reliably. You are accessing this site via HTTP. We strongly suggest you configure your server to require using HTTPS instead as described in our security tips. No memory cache has been configured. To enhance your performance please configure a memcache if available. Further information can be found in our documentation. Your PHP version (5.4.45) is no longer supported by PHP. We encourage you to upgrade your PHP version to take advantage of performance and security updates provided by PHP. I would like these to go away and run on https, please let me know if someone is capable of completing this task.
