Modules & Extensions

PDO driver is very important so it must enabled. Without this, the script will not connect to the database hence it will not work at all. If this verify fails, you will need to contact your web host and ask them to either enable it or configure it properly.
cURLEnabled
cURL is used to interact with external servers and APIs.
MbstringEnabled
Mbstring is required for correct encoding.
GD LibraryEnabled
GD library is needed to generate QRs.
ImageMagickEnabled
ImageMagick library is not required and you can proceed with installation. This extension is needed for advanced QRs. You can still generate QR codes without this extension but if you want to have advanced styling, this is needed. We recommend Imagick version 7.1.
