```
#### Solution 2: Check script loading
Verify Shoplift is properly initialized:
1. In browser console, type: `window.shoplift`
2. Press Enter
3. Should return an object (not `undefined`)
4. If undefined, check theme.liquid for script tag
#### Solution 3: Validate element structure
Ensure proper implementation by checking:
* Attributes are on the price-containing element directly
* No JavaScript replaces HTML after page load
* CSS isn't hiding elements with attributes
#### Solution 4: Clear all caches
Sometimes aggressive caching causes issues:
* Clear browser cache and cookies
* Purge Shopify theme cache via admin
* Clear CDN cache (Cloudflare, etc.)
* Disable performance optimization apps temporarily
#### Inconsistent price display
When some prices work while others don't, you're dealing with incomplete implementation across your theme.Common Symptoms:
* Some products show test prices, others don't
* Same product shows different prices in different locations
* Prices flash between values during load
#### Audit all price locations
Themes display prices in numerous locations. Check these commonly missed areas:
* **Quick view modals** - Often loaded via AJAX
* **Instant search results** - Dropdown search previews
* **Recently viewed sections** - Dynamic product displays
* **Product recommendations** - Automated suggestions
* **Mobile-specific templates** - Separate mobile code
* **Dynamically loaded content** - Any AJAX-loaded prices
#### Check for duplicate displays
Run this diagnostic to find all tagged prices:
```liquid
// Find all price attributes
const prices = document.querySelectorAll('[data-sl-attribute-p]');
console.log(`Found ${prices.length} tagged prices`);
prices.forEach(p => {
console.log(p.textContent, p.getAttribute('data-sl-attribute-p'));
});
```
This reveals missed displays or incorrect duplicates.
#### Review theme updates
If prices suddenly stopped working:
1. Check if theme was recently updated
2. Compare current templates with backup
3. Re-add missing attributes to new sections
#### Prices wrong on specific devices
Device-specific issues usually stem from responsive design using different markup for different screens.
#### Check responsive templates
Look for:
* Files with "mobile" in the name
* Device-specific sections
* CSS media queries hiding/showing elements
#### Verify mobile-specific code
When different markup exists for devices, tag both:
```liquid
{{ product.price | money }}
{{ product.price | money }}
```
### Cart and checkout Issues
Cart pricing is critical—this is where customers make final decisions. Any discrepancies here can cause abandonment or support issues.
#### Cart shows original prices
Common Symptoms:
* Product pages show test prices correctly
* Cart reverts to original prices
* Checkout totals don't match expectations
#### Verify cart transform function
For Shopify Plus stores using Cart Transforms:
* Confirm you're on Shopify Plus (required)
* Check Cart Transform is enabled in admin
* Look for conflicting cart modification apps
#### Check cart template implementation
Remember these cart-specific rules:
* Cart totals should NOT have data attributes
* Only individual product prices need marking
* Standard Shopify cart structure works best
#### Test cart isolation
To identify conflicts:
1. Temporarily disable cart-related apps
2. Check if prices display correctly
3. Look for custom JavaScript modifying cart
4. Verify AJAX updates reflect test prices
#### Checkout price mismatches
When cart and checkout differ, you're experiencing transform conflicts.
#### Validate cart transform execution
Test progressively:
1. Single product (basic functionality)
2. Multiple test products (calculations)
3. Mixed test/non-test products (partial scenarios)
#### Check for app conflicts
Common conflicting app types:
* Subscription apps - Maintain own pricing logic
* Wholesale/B2B apps - Override standard prices
* Custom checkout scripts - Modify prices
* Multi-currency apps - Perform own calculations
### Test configuration problems
Configuration issues prevent tests from being created or saved properly.
#### Can't select products
When products don't appear in the selection drawer:
#### Check product status
Products must meet these criteria:
* Status: "Active" (not draft/archived)
* Published to online store channel
* Not hidden from sales channels
#### Resolve data issues
Common selection problems:
* Recently added products need sync time
* Special characters in titles affect search
* Try searching by SKU instead
* Verify account permissions
#### Test won't save
Save failures typically indicate validation errors.
#### Validate requirements
Ensure:
* At least one price changed per product
* Test has a name
* Traffic allocation totals 100%
* No products in other active tests
#### Check browser issues
Try these solutions:
* Save from different browser
* Disable browser extensions
* Check network connectivity
* Clear browser cache
### Third-party app conflicts
Many apps can interfere with price testing by displaying their own calculated values.
#### Currency converters
These apps pull from Shopify's API, showing the highest price regardless of test variant. Solutions:
* Hide converter during tests
* Update displays via converter API if available
* Use CSS to manage visibility
* Contact app developer for integration
#### Volume pricing apps
Bulk discount apps override test prices with tier calculations. Workarounds:
* Temporarily disable for test products
* Adjust rules to respect test prices
* Limit testing to single quantities
* Document expected behavior for support
#### Review and loyalty apps
These display prices in widgets that don't update with tests. Considerations:
* They show highest price from API
* Won't affect actual purchases
* May confuse customers
* Consider hiding or adding disclaimers
### Performance issues
#### Slow page loads
If your site feels slower after launching a test, the issue likely isn't the test itself. Data attributes have zero performance impact—they're standard HTML that browsers handle efficiently.
#### Check implementation
Look for:
* JavaScript errors blocking other scripts
* Infinite loops in price update logic
* Console errors indicating problems
#### Review other changes
Performance issues often coincide with:
* Recently installed/updated apps
* Theme modifications
* Server infrastructure issues
* CDN or caching problems
### Emergency procedures
Knowing when and how to pause a test prevents customer frustration and lost sales.
#### When to pause a test
Pause immediately if:
* Checkout is broken, preventing purchases
* Customers see wrong prices at payment
* Calculations are incorrect (taxes, totals)
* Major display issues affect most users
#### How to pause
1. Navigate to active test in Shoplift
2. Click "Pause Test" button
3. Confirm the action
4. Prices revert to defaults immediately
#### Post-pause actions
After pausing:
1. Document thoroughly - Screenshots and examples
2. Test in preview - See if issue persists
3. Fix root cause - Don't just retry
4. Re-launch carefully - Monitor first hour closely
