Diagnostic Steps
Step 1: Identify the Problem
Questions to Ask:
- When did the issue start?
- Does it happen on all pages or specific ones?
- Is it browser-specific?
- Does it occur on mobile, desktop, or both?
- Can you reproduce it consistently?
Step 2: Check Browser Console
- Open your site
- Press F12 (or right-click > Inspect)
- Go to Console tab
- Look for red error messages
- Note any warnings or failed requests
Common Errors:
Uncaught ReferenceError: X is not defined- Script not loadedFailed to load resource- File not found or blockedBlocked by CORS policy- Cross-origin issue
Step 3: Test in Incognito/Private Mode
Many issues are caused by:
- Browser extensions (especially ad blockers)
- Cached files
- Cookie conflicts
Test:
- Open an incognito/private window
- Visit your site
- Check if the issue persists
Step 4: Check Squarespace Version
Squarespace 7.0 and 7.1 behave differently.
Identify Your Version:
- Log in to Squarespace
- Look at the template name
- Check if you have access to "Fluid Engine" (7.1 only)
Or check the <body> class:
- 7.1:
<body class="squarespace-7.1"> - 7.0: Various template classes
Step 5: Review Recent Changes
Check:
- Recent Code Injection updates
- New plugins or integrations
- Template changes
- Squarespace platform updates
How to Check:
- Settings > Advanced > Code Injection - review all sections
- Check activity log if available
- Review any custom CSS
Common Quick Fixes
Fix 1: Clear Cache
Squarespace Cache:
- Changes can take a few minutes to propagate
- Try adding
?nocacheto your URL - Log out and back in to Squarespace
Browser Cache:
- Hard refresh: Ctrl+Shift+R (Windows) or Cmd+Shift+R (Mac)
- Clear browser cache completely
- Test in incognito mode
Fix 2: Disable Conflicting Code
If you recently added custom code:
- Go to Settings > Advanced > Code Injection
- Comment out recent additions:
<!-- Temporarily disabled
<script>
// Your code here
</script>
-->
- Save and test
- Re-enable code piece by piece to identify the culprit
Fix 3: Check Mobile Display
Test mobile-specific issues:
- Use browser DevTools device emulation (F12 > Device Toolbar)
- Test on actual mobile devices
- Check both portrait and landscape orientations
- Verify touch interactions work
Fix 4: Validate Code Syntax
Common syntax errors:
- Missing closing tags (
</script>,</div>) - Unmatched quotes (
"vs') - Missing semicolons in JavaScript
- Invalid CSS selectors
Tools:
- JavaScript Validator
- HTML Validator
- Browser console error messages
Platform-Specific Considerations
Squarespace 7.0
Characteristics:
- Traditional template system
- More stable DOM structure
- Template-specific quirks

Common Issues:
- Template-specific CSS conflicts
- YUI framework compatibility
- Less responsive than 7.1
Squarespace 7.1 (Fluid Engine)
Characteristics:
- Modern, flexible page builder
- Dynamic content loading

- Use more general CSS selectors
- Test both initial load and navigation
