Snapshots on Archive.org not working with Volto based Plone Pages | and ways to Workaround

[acsr]

The bug

Snapshots of Volto based pages on Archive.org are not working and empty.

TODO: @davisagli @polyester Please point to exiting tickets, I did not find them

Purpose of this Ticket

I share my recent success to archive Zotero Snaphots on Archive.org

• Zotero 7 uses the technology behind https://www.getsinglefile.com/
• They inject a Javascript snippet at the end of the page from the Browser Plugin side (https://www.getsinglefile.com/ Chrome Addon, Zotero Connector) to make sure the whole page can be loaded.

This does not help to properly cite on archive.org under the correct URL and capture greater amounts of pages.

The issue should be fixed inside of Volto or by adding a Volto Patch Addon, that fixes the issue until the next release adressing the point.

To Reproduce

Steps to reproduce the behavior:

1. Go to https://archive.org
2. Click on Web in the top left menu
3. Enter a target URL in the right Save field in the Dropdown Megamenu. or go directly to https://web.archive.org/save and enter url into the field
4. Save / trigger a snapshot

Expected behavior A snapshot is taken, you can see the thumbnail, you can visit and browse the snaphot.

Issues

• A DSGVO Banner is spoiling the capture and cannot be removed in the loaded page during capture
• The site is not fully hydrated available when archive.org tries to capture the content

Possible Workarounds

• catch calls by archive.org and
  • block the DSGVO banner (not a Volto issue)
  • force a fully hydrated version of the page

Screenshot of the failure

If applicable, add screenshots or videos to help explain your problem.

Software (please complete the following information):

• OS: [macOS]
• Browser [chrome
• Volto 18.22.0
• Plone 6.1.1
• plone.restapi 9.13.3
• @kitconcept/volto-light-theme 6.0.1

Additional context

The issue was mentioned by @polyester during beethoven sprint 2025. The same may occur with httrack snapshots, but not tested by me.

further issues on Archive org

• The capture may be visible a short time, but is spoiled by the DSGVO Banner.
• After Scrolling down a successful display, you cannot scroll back
  • I cannot reprocue if the display was possible due to my personal setup 7 existing cookies or cache data
  • The display cannot be reproduced in a save way suitable for the purpose of archiving.

(very Dirty) Workaround

For me using current Zotero 7 to capture single file snapshots of a Volto page is working fine!

• you can find and display a successful snapshot of the above page using Zotero in the public Plone library on zotero:
  • https://www.zotero.org/groups/3197/plone/items/FC8T7KRT
• You can watch the attachment in the browser by logging in using any account into zotero and using the temporary link displayed when hovering over the snapshot attachment of the item in the right sidebar
  • Link starts with https://files.zotero.net/ and contains a log UUID that expires for others
• I could use this link to capture a snapshot from Archive.org that ia publicly available under:
  • This URL is very long! https://web.archive.org/..

@acsr https://github.com/plone/volto/issues/7132 was the issue that Paul opened during the Beethoven Sprint. (The fix was merged but not released yet.)

As for the DSGVO banner, maybe it is possible to hide it by setting similar cookies (confirm_cookies=1 etc.) on archive.org to what is set on tagung.plone.de after you click through the banner?
