Quiz Not Loading

If the quiz container appears on your page but the quiz never loads — or is stuck on a loading spinner — there is usually a JavaScript conflict, a network issue, or a browser-level problem. Work through this guide to identify the cause.

What "Not Loading" Means

This guide covers situations where:

The quiz container appears on the page (a space or loading spinner is visible)
But the quiz content — questions, answers, buttons — never appears
The spinner rotates indefinitely or the page shows a blank white space

If the quiz is not visible at all (no container, no space), see Quiz Not Showing on Shopify Store instead.

Step 1: Check for JavaScript Errors in the Browser Console

JavaScript errors are the most common cause of a quiz that loads the container but never renders content.

Open your quiz page on the storefront
Press F12 (or right-click and choose Inspect) to open the browser developer tools
Click the Console tab
Reload the page while watching the console for red error messages
Look for errors referencing Quizify, or errors that appear at the same time the quiz would normally load

If you see errors, note the error message text — it will help identify the cause.

Step 2: Test in a Different Browser or Incognito Mode

Browser extensions can interfere with JavaScript and prevent quizzes from loading.

Open the quiz page in an incognito or private browsing window (which disables most extensions)
Also test in a different browser (Chrome, Firefox, Edge, Safari)

If the quiz loads in incognito but not in normal mode, a browser extension is likely the cause. Disable extensions one by one to identify which one is causing the conflict.

Step 3: Check for Conflicts with Other Apps

Third-party Shopify apps that inject JavaScript — such as popups, chat widgets, review apps, or loyalty programs — can sometimes conflict with Quizify.

To test:

Temporarily disable other Shopify apps (particularly those that add scripts to the storefront)
Reload the quiz page
If the quiz now loads, re-enable apps one at a time to identify the conflicting one

Contact the conflicting app's support team or Quizify support with the conflict details.

Step 4: Test on a Slow Connection or Different Network

Sometimes a quiz fails to load due to network conditions — particularly if quiz assets (images, scripts) are loading slowly.

Test on a different network (switch from WiFi to mobile data or vice versa)
Test with browser developer tools set to simulate a fast connection

If the quiz loads on a faster connection, large unoptimised images in the quiz may be causing a timeout.

Step 5: Check the Quizify App Embed

A partially enabled app embed can cause the quiz to appear as a container but fail to load properly.

Go to Shopify admin → Online Store → Themes → Customise
Check App embeds and confirm Quizify is fully enabled
Save and reload the quiz page

Frequently asked questions

I see a blank space where the quiz should be.

The quiz container is rendering, but the quiz content is not. This is typically a JavaScript error. Open the browser console on the page with the blank space and check for errors. Also, confirm that no custom CSS on your theme is hiding the quiz container with display: none or visibility: hidden.

The loading spinner shows, but the quiz never appears.

This is almost always a JavaScript conflict or error. Open the browser console (F12) while loading the quiz page and look for red error messages. A conflicting app script or a Quizify script error will typically appear there.

The quiz doesn't load on mobile but works on desktop.

Mobile browsers handle JavaScript slightly differently than desktop browsers. Check for console errors on mobile using remote debugging (for Android) or Safari Web Inspector (for iOS). Also check whether any quiz images are very large — these can cause mobile load failures on slower connections.

The quiz loads on the first visit but not on return visits.

This may be a caching issue. Your browser or a CDN may be caching a broken state. Hard refresh (Ctrl+Shift+R / Cmd+Shift+R) and test in incognito mode to rule out caching. If the issue persists, check whether any service workers or aggressive caching in your theme are involved.

The quiz loads sometimes but not always — what's wrong?

Intermittent loading issues are typically caused by network conditions or an unreliable JavaScript dependency. Check whether the issue correlates with specific browsers, devices, or times of day. Also, review whether recently installed apps or theme changes coincide with when the issue started.

The quiz worked before but stopped loading after I installed another app.

This is a JavaScript conflict. The newly installed app is likely injecting a script that conflicts with Quizify. Temporarily disable the new app and reload the quiz page to confirm. If the quiz loads again, contact both app support teams to find a resolution.
