A few things need to be done at the server level to allow wallets to connect to the website.
The plugin uses the Cardano Wallet Serialization Library as a part of the core of its functionality. As a result, it requires a particular file WASM to be loaded on the server. By default, web servers don’t have this file type enabled, and manual enabling is required.
This tutorial will show you how to add the required WASM file type to your htaccess file on the SiteGround server to allow for the file to be loaded.
These instructions will vary from hosting type to hosting type, and we recommend using SiteGround as it has been tested for compatibility to work with CardanoPress.
