We recommend you to use the latest stable version of Joomla to ensure all known bugs and security issues have been already fixed. The template will only function properly on Joomla 3.x and newer versions.
To prevent problems with used extensions (mostly components) and installation freezes (never ending process) use following settings:

• PHP 5.6 or PHP 7.x (suggested)
• MySQLi 5.5+ OR PostgreSQL 9+

Note! Supports for PHP 5.3 and 5.4 ended.
Our SP PageBuilder component also requires at least PHP 5.6 or later. 
To use QuickStart, please use these PHP settings:

• memory_limit --> at least 64M (128MB)
• max_execution_time --> at least 240 (by default is set to 30 seconds only.)
• Magic Quotes GPC off

These mentioned above settings of PHP are strongly recommended for Joomla!  to ensure full compatibility and website security with the latest version of Joomla!: 

In most cases, those values change in php.ini or .htaccess file. Please contact your web hosting service provider to be sure that your server complies with the requirements or to ask them where/how to change above PHP settings.

About recommended browser we suggest to use the latest version of Firefox, Safari, Chrome or Internet Explorer 10+/Egde. Please remember that Internet Explorer versions 8 and older are NOT supported anymore also by Microsoft company.
