Hi @isabela59185144,
Thank you for reaching out to the community!
To better assist you with this issue, could you please let us know which version of InDesign you’re currently using and the details of your operating system? Additionally, it would be helpful if you could explain in more detail what you mean by the files being "no longer visible." For instance, when you click on the links, do you encounter any error messages, such as a 503 error, or does the page simply remain blank and white? Confirming these details will give us a clearer picture of the issue and help us identify potential solutions.
We appreciate your patience and look forward to assisting you further!
Thanks,
Abhishek Rao
