Common implementation mistakes and how to catch them

Changing the official graphic

Recreating the notice in a page builder, replacing colours, cropping fixed elements or translating text inside the artwork breaks the source-controlled workflow. Use the Commission files and preserve aspect ratio, colour and QR-code integrity.

Testing only one storefront path

A desktop product page does not cover a mobile Checkout Block, translated cart or page-builder template. Build a matrix around the store’s real product types, languages, templates and customer states. Recheck after cache, theme and checkout updates.

Turning implementation into a legal claim

Avoid badges or copy claiming certification, guaranteed compliance or EU endorsement. The presence of a graphic cannot establish every legal obligation. Keep technical evidence and obtain appropriate professional review.

Another common failure is stale documentation: a privacy page may still promise no external requests after a separately versioned licensing service is introduced. Match every statement to the version actually sold, and keep unreleased behaviour clearly labelled as a candidate.

• Do not confuse the legal notice with GARAN.
• Do not expose a paid ZIP in public assets.
• Do not make shopper requests depend on a licence server.
• Do not let language failure break checkout.

Mistaking post-purchase proof for pre-purchase placement

An order-received page or confirmation email occurs after the purchasing decision. Neither stable Notice27 1.2 nor the current private candidate provides production order-received or transactional-email placement. Do not use a successful test order as evidence that the notice was prominent on the product, cart or checkout path that the shopper actually used.

The real Notice27 1.2 evidence deliberately shows an order-received page with no injected notice. That negative evidence matters: it prevents a fictional design or future idea from leaking into a current product claim. The same discipline should be used in release notes, screenshots, sales pages and agency handoffs.

A compact regression routine

After a theme, WooCommerce, checkout, multilingual or cache change, repeat a compact but representative journey: simple product, variable product, populated cart, checkout validation, narrow mobile view and every active storefront language. Inspect console and first-party requests, then capture a dated screenshot and record the installed version.

Automated checks can catch missing images, duplicate output and overflow, but human review is still needed for prominence, language appropriateness, QR access and obstruction by sticky interfaces. Keep failed rows in the evidence record so unresolved risks remain visible.

Make the expected unsupported surfaces part of the regression. If stable 1.2 begins appearing on shop/category, order-received or email without a deliberate release change, that is a defect—not bonus coverage. Negative assertions keep future plans and private candidate work from altering the product sold today.

Finally, compare public copy with the tested package. A landing page that mentions a trial, portal or email placement can create a product defect even when the PHP is correct. Release review should cover website, documentation, screenshots, schema and the ZIP as one claim surface.

Assign every finding a clear owner and retest condition. Artwork defects go back to the official source workflow, language defects to configuration and cache review, and missing placements to the active WooCommerce template path. Avoid a generic “plugin issue” label that hides whether the problem is legal interpretation, content, integration or theme behavior.
