Use it in your project
Suggest similar published pages and nearby sections while keeping the correct 404 response. Visitors can follow the suggestions with or without JavaScript.
Picture it on your site
For a renamed section, try an old URL and review whether the suggested published pages genuinely help the visitor continue. Keep the correct missing-page response and test the ordinary links without JavaScript. Suggestions are a recovery aid, not a replacement for deliberate redirects when the team knows the exact new destination.

Help people find your content
- Match missing paths to site-scoped public URLs.
- Keep unpublished pages out of suggestions.
Is this right for your project?
Help a reader complete a task
Start with the phrases and pages a visitor needs, not a dashboard score. Check that published content is discoverable, that its title and description make sense in context, and that the destination answers the question. Search and SEO tooling can support those tasks, but it does not write the content strategy or guarantee a ranking. Your team still decides what deserves to be published.
Check the public result
Use a known published page and an unpublished comparison to test the supported output. Include a moved URL, an alternative language or an empty result where that applies to your project. Review the actual response or generated document, not only the editor settings. Any external search account, index or crawler has its own setup and refresh behaviour to account for.
You may ask Capell for a full refund within 14 days of purchase. Requests are assessed case by case against the recorded order, access and support history. This applies to live paid first-party packages; third-party author sales have separate terms. Read the Refund Policy
Your renewal price stays locked while you renew continuously, including during the grace period. After a full lapse, renewal uses the current list price.
Marketplace listings can describe install impact and data access.
This installs as a Composer package. Check its removal guidance and retained-data policy before uninstalling it.
Paid checkout adds access to the purchasing account after payment. Add a free package to your account, then review compatibility and site impact before installing it.

Before checkout
Know who owns access and what happens next
Payment, customer account ownership, site activation, and package access are separate steps. The checkout reference lets support trace a problem without moving the licence to another account.
Who processes the payment and taxes?
Lemon Squeezy is the seller and hosts paid marketplace checkout. Any VAT due is calculated and added by Lemon Squeezy at checkout, and Lemon Squeezy issues the tax receipt. Capell does not collect card details; it activates the matching marketplace licence after payment is confirmed.
Which account owns the licence?
The signed-in customer account that completes checkout owns the Capell licence, support history, and future install access. Capell surfaces a link to the tax receipt issued by Lemon Squeezy. Use the intended organisation account before paying.
How does the site receive package access?
The install flow connects the licence to the requesting site. Paid and private packages then use authenticated Composer access from the customer account that owns the licence.
What happens if checkout is cancelled or expires?
No licence is created until Lemon Squeezy confirms payment. After a cancellation or expired quote, return to the same marketplace listing and start a fresh checkout so price and package details are recalculated.
How do I request a refund?
Use the order link on the Lemon Squeezy receipt and request the refund through the Lemon Squeezy order receipt. If the receipt or order link is unavailable, contact Capell support so the payment and access record can be traced.
What should I do if access does not appear?
Keep the checkout reference from the page or receipt and contact support before trying another account. Support can trace the payment, customer account, licence, and connected site from that reference.
