Site Builder Fixes - 2026-02-22

Issues Fixed

1. YouTube Error 153 ✅

Problem: "Video player configuration error" when embedding YouTube videos

Root Cause: YouTube Error 153 means "The owner of the requested video does not allow it to be played in embedded players with autoplay enabled." Many content creators disable autoplay in embeds for revenue/engagement reasons.

Fix Applied:

• Removed autoplay=1 parameter from YouTube embed URLs
• Changed from: https://www.youtube.com/embed/{ID}?autoplay=1&mute=1&loop=1&playlist={ID}
• Changed to: https://www.youtube.com/embed/{ID}?mute=1&loop=1&playlist={ID}&rel=0
• Also removed autoplay from Vimeo embeds for consistency

File Modified: /home/jknapp/code/site-builder/js/editor.js (lines ~1084-1094)

How to Test:

1. Refresh the site builder
2. Add a Video block
3. Paste any YouTube URL (e.g., https://www.youtube.com/watch?v=dQw4w9WgXcQ)
4. Video should now load without Error 153
5. Click play button manually to start playback

2. Test Elements from Previous Sessions ✅

Problem: Old test content persists in the editor even after page refresh

Root Cause: GrapesJS autosaves to localStorage (sitebuilder-project key) and auto-loads on startup

Fix Applied:

1. Updated Clear Canvas button to also clear localStorage
2. Created dedicated clear-data page for easy reset

Files Modified:

• /home/jknapp/code/site-builder/js/editor.js - Updated btn-clear handler
• /home/jknapp/code/site-builder/clear-data.html - New utility page

How to Clear Test Data:

Option A - Use Clear Canvas button:

1. Open site builder
2. Click "Clear" button (trash icon) in top nav
3. Confirm the dialog
4. Refresh the page for a clean start

Option B - Use clear-data.html page:

1. Open http://localhost:<port>/clear-data.html (or just open clear-data.html)
2. Click "Clear All Data"
3. Automatically redirects to clean editor

Option C - Browser DevTools:

1. Open browser DevTools (F12)
2. Go to Application/Storage tab
3. Expand "Local Storage"
4. Find your site-builder domain
5. Delete sitebuilder-project and sitebuilder-project-preview keys
6. Refresh page

3. Windows Security Warning on Export ✅ SOLVED!

Problem: Windows blocks the exported ZIP file and index.html with "potentially unsafe" warning, won't even let you extract

Root Cause: Windows SmartScreen scans all downloaded files and blocks HTML/ZIP by default

🎉 NEW SOLUTION - "Copy HTML" Button:

Added a clipboard export feature that completely bypasses Windows security!

How to use:

1. Click Export → Copy HTML button (NEW!)
2. Open Notepad
3. Paste (Ctrl+V)
4. Save as index.html
5. Open in browser - NO WARNINGS! ✅

Why this works:

• No file download = No SmartScreen scan
• You create the file manually = Windows trusts it
• Pure text clipboard = Completely safe

Files Modified:

• /home/jknapp/code/site-builder/index.html - Added Copy HTML button to export modal
• /home/jknapp/code/site-builder/js/editor.js - Added clipboard copy handler
• /home/jknapp/code/site-builder/WINDOWS_EXPORT_FIX.md - Complete usage guide

Alternative Methods (if you still want ZIP):

Option 1 - Unblock ZIP First:

1. Right-click the downloaded .zip file
2. Select "Properties"
3. Check "Unblock" at the bottom
4. Click Apply/OK
5. NOW extract - should work

Option 2 - Unblock After Saving:

1. Use Copy HTML method
2. If saved file still shows warning
3. Right-click → Properties → Unblock

4. Video Background Section - Missing Video URL Field ✅

Problem: "Section (Video BG)" block doesn't show where to enter the video URL

Root Cause: The Video URL trait was only on a deeply nested inner element (bg-video-wrapper), not on the section itself that users select.

Fix Applied:

• Created new component type video-section that detects the outer section element
• Added Video URL trait directly to the section (shows in Settings panel)
• Propagates URL automatically to the inner video wrapper element
• Updated placeholder text: "Click this section, then add Video URL in Settings →"

File Modified: /home/jknapp/code/site-builder/js/editor.js (added video-section component type)

How to Use:

1. Drag "Section (Video BG)" onto canvas
2. Click the section to select it
3. Look at Settings panel on the right → Video URL field should be visible
4. Paste YouTube/Vimeo/video file URL
5. Video loads automatically!

Full Documentation: See VIDEO_BG_FIX.md for complete usage guide

Additional Notes

YouTube Embed Best Practices:

• Always test with multiple videos (some creators have stricter embed policies)
• If a specific video still won't embed, it's the creator's restriction, not a bug
• Consider adding a fallback image/message for restricted videos

localStorage Size Limit:

• Browsers limit localStorage to ~5-10MB
• Large projects may hit this limit
• Consider implementing export/import of projects as JSON files
• Could add warning when approaching limit

Export Improvements for Future:

• Add option to export as GitHub Pages-ready structure
• Include a README.md with deployment instructions
• Option to export with/without external dependencies
• Create a "Deploy to Netlify/Vercel" one-click option

Quick Reference

Open Site Builder:

cd /home/jknapp/code/site-builder

Clear All Data:

# Open clear-data.html in browser
# OR manually:

Re-test YouTube:

Try these test URLs:
