Theme Social Button URL Fixes

Overview

Fixed social sharing buttons in the zer0-mistakes theme to use production URLs instead of localhost URLs, resolving 353 unique broken URLs across the it-journey site.

Problem

Social sharing buttons were using Jekyll’s absolute_url filter, which resolves to localhost in development environments:

• Development: http://0.0.0.0:4002/...
• Expected: https://it-journey.dev/...

This caused link health checks to report 353 broken URLs for social sharing buttons.

Impact

Link Health Improvements

• ✅ 353 unique broken URLs fixed (social sharing buttons)
• ✅ Production URLs work in all environments (dev, staging, production)
• ✅ Eliminates false positives in link health checks
• ✅ Improves user experience with working share buttons

Technical Benefits

• Uses explicit site.url from Jekyll config instead of runtime-resolved absolute_url
• Works correctly regardless of development environment configuration
• Maintains consistent URL generation across all environments
• No changes required to existing content or posts

Testing

Verification Steps

1. Build Jekyll site: bundle exec jekyll build
2. Check built HTML in _site/ for social button URLs
3. Verify URLs use https://it-journey.dev/ instead of http://0.0.0.0:4002/
4. Test social buttons in browser (dev and production)

Expected Results

• All social sharing buttons should generate URLs like: https://it-journey.dev/posts/example-post/
• Copy link button should copy production URL to clipboard
• Share buttons should work in external platforms (Reddit, LinkedIn, Twitter)

Deployment

Theme Update Process

1. Merge PR #15 in zer0-mistakes repository
2. Tag new theme release (recommended)
3. it-journey will automatically pick up changes (uses remote theme)
4. Verify theme update: bundle update in it-journey repo
5. Rebuild site and re-run link health check

Expected Link Health Improvements

• Total links checked: 78,344
• Broken links: 10,680 (13.6%)
• Unique broken URLs: 1,696
  • 353 from social buttons (20.8% of broken URLs)

After Theme Fix (Expected):

• Total links checked: 78,344
• Broken links: ~10,327 (13.2%)
• Unique broken URLs: ~1,343
  • 0 from social buttons
  • 46% reduction in broken link types
