+## Fixing "Old" Attachments
+
+Prior to December 2018 file attachments used a different method of encrypting their data. We have since moved to a newer, better way of encrypting file attachments. Any attachments that use the older encryption method will be labeled with an {% icon fa-exclamation-triangle %} alert icon in your vault listing. You should upgrade these old attachments to the newer method of encryption so that other account-related features can function properly.
+
+1. Open the page for editing your attachments (see above).
+2. Click the **Fix** button next to the old attachment. This process will download the attachment, re-encrypt it using the new encryption method, re-upload the attachment back to your vault, and delete the old version of the attachment.
+
+Once an attachment has successfully been upgraded, the {% icon fa-exclamation-triangle %} alert icon and fix button should disappear.
