Nova NextGen Requirements

Nova NextGen Getting Started General Information

Nova NextGen's requirements are fairly simple and straightforward, but you'll want to verify that any server you're attempting to install it on have the requirements listed below.

The first step of Nova's installation process is to check and make sure it can run on the server it's on. If any of those checks fail, you'll be shown what failed and will need to either contact your host about upgrading/enabling those items or find a host that supports the requirements.


Nova NextGen requires a server running PHP 5.5.9 or higher. Historically, many shared hosts are very slow to update to newer versions of PHP. You can contact your host about ways to use PHP 5.5 for your account. If it is not an option, you may need to look at switching hosts if you want to run Nova NextGen.

PHP Extensions

In addition to PHP 5.5, several PHP extensions must be enabled for all of Nova's features to work. Those extensions include:

  • Mycrypt PHP extension
  • OpenSSL PHP extension
  • Mbstring PHP extension
  • Tokenizer PHP extension

Note: As of PHP 5.5, some OS distributions may require you to manually install the PHP JSON extension. Please contact your host about this if you have any questions.


Since Nova is a database-driven system, it needs a database in order to run. Unlike previous versions of Nova, Nova NextGen is not tied exclusively to MySQL. In addition to MySQL, you can also use PostgreSQL to run your Nova site if you so choose.

Additionally, Nova NextGen can also use SQLite for a fast, quick file-based database instead of needing to run a full MySQL/PostgreSQL database. This is only intended for development purposes and is not suitable for running a site in a production environment!

A Browser

Since Nova is web-based software, you'll need a browser in order to use it. These days, there are a lot of browsers out there and most of them should work, but some of the older generation browser aren't supported because of their lack of support for technologies and tools used in Nova.

Our recommendation is to use Google Chrome (version 30 or higher) or Mozilla Firefox (version 20 or higher). In addition, we also support Safari as well as Internet Explorer 10 and higher. Make sure you have JavaScript and cookies enabled as many of Nova's features require them.
