Requirements For Avada
To use Avada, please make sure you are running WordPress 4.6 or higher, PHP 5.6 or higher, and MySQL 5.6 or higher (for legacy environments also PHP versions 5.3.x will work but it is recommended to be on at least PHP 5.6 and more preferably PHP 7.0+ WordPress recommends PHP 7.3 at minimum).
Important Note About Avada + PHP Versions
Here is a summary of PHP version compatibility with Avada and our reasoning behind it. Avada is fully compatible with PHP 5.3+ since many hosts are still using that PHP version, however ThemeFusion and WordPress recommends using PHP 7+.
With the exception of demo imports, Avada is even compatible with earlier versions of PHP 5.2.x, this means Avada will work with those earlier versions of PHP 5.2.x, but the demo imports will not work. We officially dropped support for PHP 5.2 because first and foremost it has reached the end of its life cycle and because of performance and functionality reasons. However, because we are dedicated to our customer base, we fixed some known issues with PHP 5.2.x so any Avada users on PHP 5.2.x can use Avada without issues. But again, please do update your PHP version.
Furthermore, and most important, WordPress recommends PHP 7.0 and for good reason. Other PHP versions have reached the end of their life cycle and may expose your site to security vulnerabilities. There is a significant reason to no longer use old PHP versions, always update to the latest versions.
Also, PHP 5.3, 5.4 and 5.5 have reached end of their life cycle and shouldn’t be used at all. PHP 5.6 will reach end of active support by the end of this year as well. While those versions should not be used, we do support them and they will work with Avada. However, since they have reached the end of their life, issues that may arise can only be fixed to a certain extent. It's good practice to always stay up to date with these things.
Issues that you may experience are because certain hosting plans do not care about such things, which causes a lot of issues for their customers and the themes they use. The themes are not to blame, it is the hosts who will not stay up to date with the latest PHP versions.
Since the only actively supported PHP versions from January 2017 onwards will be 7+, these should be the versions of choice and you should always look for a host who actively updates their PHP and MySQL versions. We regularly test the latest versions and ensure that Avada runs smoothly on them and does not face any issues.

Recommended PHP Configuration Limits
Many issues that you may run into such as: white screen, your demo import fails, empty page content with Fusion Builder and other similar issues are all related to low PHP configuration limits. The solution is to increase the PHP limits. You can do this on your own, or contact your web host and ask them to increase those limits to a minimum as follows:
How To Verify Your Current PHP Limits
You can verify your PHP configuration limits in the System Status tab in the Welcome Screen area. Look in the left sidebar for the Avada > System Status tab. You can also check them by installing a simple plugin found here. In addition, you can always contact your host and ask them what the current settings are and have them adjust as needed. Please note that many hosts will try to keep the PHP limits low without reason. However you are paying for it and therefore should be getting your money's worth.
