Hi there,
This issue usually created by cache plugin. It may cache download url for guest users, but those urls are unique and that’s where the issue may create.
Would you mind providing us with login credentials so we can take a closer look? Your site seems to be on Under Construction Mode. To do this, you can make a post with the following info:
– Link to your site
– WordPress Admin username / password
Don’t forget to select Set as private reply. This ensures your information is only visible to our staff.
Thank you sir
