When activating your Vcard module, it is necessary to activate the main "Slug" of your company.
The "slug" is a part of the link that allows easy identification of your link. It is divided into 3 parts, the base link, the company part (which we see here), and the user part.
To activate the company part. Go to the settings tab then the Vcard tab. Fill in the "Slug" card with your company's name as in the example.
