download link not showing up in wordpress after it has been paid for

[ Moderator note: moved to Fixing WordPress. ]

Hi,

I have a website at https://www.nourishinglolaandsage.com.au and I have an ebook for sale. I have tested it to see if I can purchase it, which I can, however it fails to provide me with a link to download it once I have paid for it.

Can you please show me how to fix this issue!

Thanks
Poppy
