Troubleshooting

Fixes for the common Event Ticketing problems — tickets not showing on your store, inventory that looks wrong or sold out, "cannot find variant" at checkout, and an event that won't save.

Most problems trace back to one of three things: the event’s Shopify product isn’t set to sell yet, its inventory was edited outside the app, or its variants were changed directly in Shopify. Find the symptom below and follow the linked fix.

Requirements: The Event Ticketing app installed.

Tickets don’t show on my store

A new event builds a Shopify product as a Draft with no sales channel, so customers can’t see it until you publish it. Set the product to Active and add it to the Online Store sales channel in Shopify admin. Both are required — Active but not on the Online Store is still hidden, and on the Online Store but still Draft is also hidden.

See Storefront visibility for the steps.

Inventory shows sold out or the wrong number

Work through these in order:

  • Product is Draft or not on a sales channel. Same fix as above — see Storefront visibility.
  • Inventory was edited on the “Adjust by” mode. On an existing event the Inventory field defaults to Adjust by, which adds to the current count instead of replacing it — so typing your target total doubles it. Switch the mode to Set to to enter an exact total. See Adjusting inventory and prices.
  • The app and Shopify disagree. The app stores the level it last pushed and doesn’t subscribe to Shopify’s inventory changes, so the two drift if inventory was changed directly in Shopify or by another app. When they differ, the event form shows a banner listing the affected variants with Shopify’s number, a Use N link per row, and a Match Shopify button to adopt Shopify’s counts at once. Pick a value and save.
  • A POS or warehouse app is resetting inventory. Some inventory integrations overwrite Shopify stock on a schedule. In Shopify admin, open the product, view its inventory history, identify the app making the changes, and configure that app to leave ticket products alone — then correct the inventory in the Event Ticketing app.

“Cannot find variant” or a product 404 at checkout

This is almost always the product not being sellable yet. Open the product in Shopify admin, set its status to Active, and confirm it’s published to the Online Store sales channel. See Storefront visibility.

A purchase limit isn’t being enforced

Minimum and maximum per-order quantities you set on a ticket are enforced in the cart and at checkout for any theme. If a limit isn’t applying, confirm the limit is set on the ticket in the Event Ticketing app — limits are per ticket, not per event. See Purchase limits.

My event won’t save

The Shopify preview on the right of the event form must resolve to valid products before you can save. Two checks fail the save:

  • Too many variants. An event can’t produce a Shopify product with more than 250 variants. The form shows an error and won’t save until the event fits. To reduce variants, remove dates or ticket types, or split the event into separate products (the Split into separate products and Split events into products by options on the preview — available only before the event is first saved).
  • A field needs attention. If the save bar reports fields need attention, the form scrolls to the first invalid field and lists every error in a banner at the bottom. Fix the flagged fields and save again. A flagged field inside a collapsed date or ticket section scrolls to the collapsed section — expand it to reach the field.

If the save still fails with a server error, contact support with the event URL.

Don’t manage the product in Shopify

Event Ticketing owns the product’s options, values, and variants. Editing them directly in Shopify breaks ticket issuance, and re-saving the event removes any variants you added in Shopify. Make all event changes — dates, ticket types, prices, inventory — from the Event Ticketing app. You can safely change a product’s status, sales channels, tax, and physical/shipping flags in Shopify.

FAQ

Can I edit inventory directly in Shopify?

You can, but the app won’t see it until you reopen the event form, and re-saving the event overwrites it with the app’s stored level. Edit inventory through the Event Ticketing app so both sides stay aligned. When they’ve already drifted, the event form’s divergence banner lets you adopt Shopify’s counts.

I added a variant in Shopify and it disappeared. Why?

Re-saving the event in the Event Ticketing app removes variants that were added directly in Shopify, because the app rebuilds the product’s variants from the event. Add ticket types in the app instead. Tickets already sold remain valid.

My event has more than 250 variants — what do I do?

250 variants per Shopify product is the app’s limit. Before first saving, you can split the event across multiple products using the split options on the Shopify preview. Otherwise reduce the number of dates or ticket types so the event fits.

Why is the split option greyed out?

Splitting an event into separate products can only be chosen while the event is new and unsaved. Once saved, the option is locked.
