Job shopify-product-tab-after-theme-update · revised 9 October 2026
Restore a Shopify product tab lost after a theme update
The agreed product-description tab opens and closes on a duplicated theme on phone and desktop while the underlying product text remains unchanged.
You might be seeing
- Product details that used to be under a tab are hidden or merged
- The product page reports a missing script after a theme update
No passwords, keys, card details or admin invites needed to start.
What usually happened
A theme update replaced a custom product-tab script or removed a JavaScript dependency the old tab needed, leaving content hard to find even though the product data remains in Shopify.
Who it’s for: Shopify store owner whose custom product-description tab disappeared after replacing a theme.
Usually starts when: The store changes theme version and its existing description tab no longer opens.
The result: The agreed product-description tab opens and closes on a duplicated theme on phone and desktop while the underlying product text remains unchanged.

Answer these without sending logins or customer data. Nothing is submitted unless you choose to contact us.
Checks you can run yourself
Compare old and new themes
Use each theme preview on the same product. Look for the tab and its text in both.
Look for: If the text is missing in both, investigate data rather than the display code.
What you get
- A tested duplicated-theme change with file list
- Before/after screenshots at phone and desktop widths and revert instructions
Included
- Identify the old custom tab and its content source
- Replace only the lost tab interaction on a duplicated theme, without relying on the removed dependency
Not included
- Whole-store theme migration
- Editing product descriptions or search ranking
- Checkout customisation
- Restoring paid app features without the app licence
How we know it’s done
Agreed with you before work starts. Each check produces evidence you keep.
The agreed product has a usable tab that reveals the same product text at 390px and 1440px in theme preview
Evidence: Two viewport screenshots and old/new text comparison
The tab can be operated by keyboard and the add-to-cart control still adds the right variant
Evidence: Recorded keyboard and cart test in preview
Sign-off. You inspect the named test result and sign off before payment. Your authorised account holder performs and verifies any live change.
If it fails. If the agreed test fails, you do not pay for this fixed scope. We hand over the findings and agree whether to stop or re-quote; no surprise work.
When it fits, and when we stop
It fits when
- A previous theme copy shows the tab working or the intended behaviour can be described
- A duplicated unpublished theme is available for comparison
We stop and tell you if
- The missing content is in an app account or licence the owner no longer has
- There is no recoverable product content or prior theme, requiring a new feature design
What could go wrong
Keep the previous code or configuration on a named test copy. The handover lists every change and its reverse; live database changes or external effects require a separate owner-approved plan.
Scroll the table sideways to read it all.
| Risk | How we handle it |
|---|---|
| Theme update overwrites custom code again | Document exact change and keep a duplicate of the tested theme. |
| A third-party tab app owns the behaviour | Confirm the original source before changing theme code; refer to app support if licensed code is missing. |
An independent reviewer checks the specific data, payment and permission risks, the redacted test result and whether the owner can safely reverse the change.
How we deliver
We arrange the work and independent review, then show you the result against the agreed checks. You keep authority over your systems.
- Compare prior and current theme markup in unpublished copies
- Restore the smallest tab control without shipping an obsolete script dependency
- Check mobile, desktop and unaffected product templates with an independent reviewer
- Hand over the reviewed change, evidence and reversal steps; the owner controls the live switch.
This is a one-off job, not emergency cover or a subscription. We confirm eligibility, the total price, a start window and a delivery date before you accept. Work starts only after agreed inputs, secure access, any licences and necessary permissions are in place. Hosting, platform and supplier charges are excluded unless the written quote includes them. No charge or booking is created by an enquiry.
Need to keep it working?
If the theme changes often, discuss a mobile, keyboard and cart regression check before each release.
Ongoing work is separately scoped and quoted: no monitoring, response-time guarantee or automatic subscription is included in this job.
Explore an ongoing engineering lane, or mention the responsibility you need in your enquiry.
What you can check
This is a new service. We have not delivered this job for a client yet.
Other ways to get this done
- Ask the original platform or app vendor whether its support can fix this under your existing plan.
- If someone already maintains this system for you, ask them to test this exact failure on a copy first.
Questions
Will you publish the updated theme?
The owner publishes after approving the duplicated-theme preview and rollback.
What if the product text itself is gone?
That is data recovery, not this tab repair. We stop before charging for this scope.
Start with an email
Send us
- Public URL and screenshot of old tab, without customer data
- Old and new theme names and approximate update date
Later, once you agree
- Owner-created unpublished theme duplicate and safe preview access
- Theme code export or collaborator access scoped to the theme
- A company-controlled secure handoff agreed before access: no live passwords, keys, private code or customer records by ordinary email.
You keep the live service, account, production keys and customer records. Agents work only on an authorised copy with synthetic data and a company-controlled handoff; a person owns Synthetic Industry and remains accountable. Your authorised account holder approves and carries out the live change.
