The download button is missing
If the button isn't showing, then this is how you can troubleshoot the problem.
1. Make sure the link column has been added correctly
First, check the columns documentation and make sure the link column has been added correctly.
2. Make sure a 'Document Link' has been added
Go to the 'Documents' section of the WordPress admin and click on any document to open the 'Edit Document' screen. Make sure a 'Document Link' has been added in the top right corner - this can either be a link to a downloadable document, or to any third party URL (for example a file on Dropbox or YouTube).
3. Is the button styling missing?
If you have selected the 'button' link style but only a text link is appearing, then this means that your theme doesn't contain styling for buttons. Please send us a support request and we will be happy to send your some custom CSS code to style the links as buttons.
