Hi Seguimiento,

Thanks for reaching out to Jotform Support. Unfortunately, our Spanish Support agents are busy helping other Jotform users at the moment. I'll try to help you in English using Google Translate, but you can reply in whichever language you feel comfortable using. Or, if you'd rather have support in Spanish, let us know and we can have them do that. But, keep in mind that you'd have to wait until they're available again.

Now, let me help you with your question. To resolve the issue, you need to disable the requirement to Login to View Uploaded Files. Let me walk you through it:

1. Login to your Jotform account.
2. Hover your mouse over your Avatar/Profile picture on the right side of the screen.
3. In the dropdown, click on Settings, or click on this link to go directly to your Settings page.
4. Now, go to the Security tab and uncheck the box next to Require Login to View Uploaded Files under the Privacy section.

Give it a try and let us know if you need any help.
