Something not working the way you expect? This guide covers the problems Composerie merchants run into most, with the fastest fix for each. It is written for anyone setting up or running a store, no technical background needed. Work through the quick checks first. Record the result of each check so you can report what remains wrong.
Run these quick checks first
Before you dig into a specific problem, run through this short list. These checks help narrow down the cause.
Hard refresh the page
Hold Shift and click the browser reload button. A normal refresh can leave an old script or cached state in place. A hard refresh can help reload browser resources; it does not publish saved edits or clear every kind of stored state. Try your product page again after the reload.
Check your browser is current
Composerie supports recent versions of Chrome, Safari, Firefox, and Edge. An out-of-date browser can break the customizer in ways that look like a bug. Update your browser, or try the page in a different one to rule it out. For the full list, see browser and device support.
Confirm the app is installed and the product is published
Open your Shopify admin and go to Apps. Composerie should appear in the list and be active. Then open the product itself and confirm it is published to your online store. A draft product, or a missing app, will not show a customizer.
If you just edited a design, check its publication
Save the design and update the existing publication for the intended store. Check that the update completed, then reload the product URL. Waiting alone does not publish saved edits.
Frequently asked questions
Here are the four questions we hear most. Each one links to a dedicated article with the full fix.
Why is the customizer not showing on my product page?
Check the publication and selected display mode, then the active theme and product block. Linked has no shopper editor. See the customizer not appearing article for the checklist.
I edited a design but my change is not showing on the storefront. Why?
Save the design, update the publication for the intended store, and check the update result before reloading. See the changes not showing article if the storefront still differs.
A customer says they cannot add a personalized product to the cart. What now?
This is usually a variant or mapping issue, or a theme conflict with the add-to-cart button. See the product will not add to cart article for the step-by-step fix.
An order came in but it did not reach my print provider. What happened?
Check the order status and timeline, its saved fulfillment route, and the provider connection. A failed print render and a failed provider submission need different recovery steps. See orders not reaching provider before retrying.
