Remote Server Requirements:

The system requirements for the remote server where the provisioning or package building process will be taking place highly depends on the size of the site being worked with. In some cases, you may find an "Allowed memory size" PHP error being thrown, which means you need to increase the PHP memory_limit value on the remote server. We recommend setting this value to 256M as a starting point and increase it only if needed.

In addition, the remote server will also need the following PHP requirements enabled:

• - PHP cURL Library
• - PHP PDO Library
• - MySQL 5.2.0 or higher
• - PHP extensions to enable: nd_mysqli, mysqlind and nd_pdo_mysql (do not to enable mysqli)
• - PHP functions to enable: curl_exec(), ZipArchive and PharData support
