Blogger Recovery Tools

A WordPress recovery toolkit for auditing and cleaning up common issues after migrating content from Blogger to WordPress.

Current plugin version: 2.5.0

🚀 Features

• Issues Detector: Scans published posts for Blogger image wrappers, remote Blogger image sources, embedded AdSense, legacy .html links, and old Blogger markup.
• Image Recovery: Removes obsolete Blogger link wrappers and imports images whose src still points to Blogger.
• HTML Cleanup: Modernizes old Blogger HTML markup:
  • Removes AdSense blocks (Tables, Scripts, and Ads).
  • Fixes malformed HTML quotes (e.g., align=""left"").
  • Resolves Blogger .html links to matching WordPress post slugs.
  • Removes an early body heading only when it exactly matches the WordPress post title.
  • Adds consistent vertical spacing to manually authored BACA JUGA link blocks.
  • Converts deprecated align attributes to modern CSS classes.
  • Modernizes table structures.
  • Converts Blogger caption tables into standard WordPress <figure> and <figcaption> elements.
• Redirect Migrator: Exports active Redirection rules to CSV and imports them through the Yoast SEO Premium redirect API.
• Paragraph Normalizer: Scans legacy div-based paragraphs, previews one post at a time, and normalizes selected Post IDs in guarded batches of up to 20.
• Dry-run by Default: Image recovery, HTML cleanup, and redirect migration preview their work without writing files or database changes.
• Explicit Apply Guard: Write operations require disabling dry-run and typing APPLY.
• Full Database Backup: Generates a temporary full SQL dump, downloads it as .sql.gz, and removes the server-side temporary file immediately.

🛠️ Installation

1. Upload the blogger-recovery folder to the /wp-content/plugins/ directory.
2. Activate the plugin through the 'Plugins' menu in WordPress.
3. Navigate to Tools > Blogger Recovery to start the process.

📋 Recommended Workflow

1. Backup your database before running any automated cleanup.
2. Run the Issues Detector to see the extent of migration issues.
3. Download a Full Database Backup and store it securely; it contains sensitive user and configuration data.
4. Run each recovery module in Dry-run mode and review its log.
5. Run Image Recovery in Apply mode only after verifying the image report.
6. Run HTML Cleanup in Apply mode; manually authored links such as BACA JUGA are resolved from their href using current post slugs and active Redirection rules.
7. Use Paragraph Normalizer on selected legacy posts, starting with one Post ID and reviewing the frontend after Apply.
8. Review unresolved .html links, export redirect CSV, then migrate valid Redirection rules to Yoast Premium.

📝 Technical Details

• AJAX Driven: Batch processing ensures the plugin can handle thousands of posts without timing out.
• Deterministic Batches: Published posts are processed in ascending post ID order.
• WordPress APIs: Uses native attachment, post update, nonce, capability, and Yoast redirect APIs.

⚠️ Compatibility Notice

This plugin handles a specific set of Blogger migration patterns and should not be assumed to support every migration scenario.

It has been tested against a real migration dataset on ranalino.co. Other websites may use different Blogger markup, permalink structures, media URLs, database configurations, or redirect plugins. Always create a backup and review the dry-run output before applying changes.
