Uploaded files not found

I have made a test page for uploading, but after I attach a file, and it’s uploaded, it is deleted again from the wpcs7_uploads folder. I read the specs and it says it’s supposed to do this (upload, attach to email, then delete from temp folder). So where is advanced cf7 db supposed to find the uploaded pictures later on?

When I go into the advanced cf7db view and see the records, there is a download link, that leads to a 404.

The files do show up as attachments in the emails.

The page I need help with: [log in to see the link]
