Since this is an extension for Joomla, it’s highly recommended to always use the latest stable version of Joomla to ensure compatibility, security, and bug fixes. This component works seamlessly with Joomla 6, 5.x, and 4.x. But on Joomla 6, it requires using the System – Behaviour – Backward Compatibility 6 plugin.

• PHP: 7.4 (minimum) or 8.x (recommended)
• MySQL: 5.6 (minimum) or 5.7, 8.x (recommended)
• Server: 64-bit server required. PHP 7+ and 8 provide full 64-bit support, including native 64-bit integers, LFS, and increased memory limits.
• PHP upload_max_filesize = 3M or more.

Browser Recommendations:

• Use the latest versions of modern browsers as Safari, Chrome, Firefox, Opera, MS Edge, or Brave.

Note: Support for Internet Explorer is limited.
