Run these checks first
They resolve a large share of issues on their own, and where they do not, the results tell support a great deal.1
Reproduce it deliberately
Confirm it happens every time, or note the pattern when it does not.
2
Test in incognito
A private window with no extensions rules out cache and browser add-ons.
3
Test another device
Desktop and mobile behave differently. Knowing which one fails narrows the cause immediately.
4
Test a clean theme copy
Duplicate the theme, strip your custom code from the copy, and retest. This separates the product from your customizations.
5
Test with the suspect app disabled
In the unpublished copy only. See App conflicts.
What to include
The last row matters more than it looks. “The spacing is slightly off on one collection page” and “no customer can check out” get very different responses, and support cannot tell which one you have from a screenshot.
Getting a screenshot that helps
- Capture the whole browser window, not a tight crop. The URL and the surrounding page carry context.
- Include the error text as text as well as an image, so it can be searched.
- For a layout problem, send both desktop and mobile.
- For anything intermittent, a short screen recording beats stills.
Security
Safe to share: your.myshopify.com domain, order number, billing email, theme version, page URLs, screenshots with personal customer data removed, and the last four digits of a payment method.
