* We validate WHMCS to run in Linux based environments running the Apache web server. Other environments such as Windows based configurations may experience compatibility issues and are not supported.
** Memory requirements vary depending upon the size and volume of activity in an installation. Your exact requirements may differ.
*** As part of PCI compliance, we recommend a SSL library capable of TLS 1.1 and/or 1.2. If using OpenSSL, version 1.0.1c or newer is recommended.
