WP Retro Version Manager – Retro Themes and Plugins simplifies managing WordPress plugin and theme versions. Whether you need to downgrade a plugin like wordpress-seo or a theme like twentytwenty due to compatibility issues, this tool lets you search, download, or install specific versions directly from the WordPress.org repository.
Key Features:
- Search Plugin and Theme Versions: Enter a plugin or theme slug (e.g.,
wordpress-seo,twentytwenty) to view all available versions. The installed version (if any) is shown at the top. - Install Older Versions: Install any version with one click, provided it is not already installed.
- Download ZIP Files: Save plugin or theme ZIPs for manual installation or backups.
- User-Friendly Interface: Clean, modern design with clear instructions.
- Safe and Secure: Uses WordPress core APIs for reliable downloads and installations.
Important Note:
If a plugin or theme is already installed, you must manually deactivate and delete it from the Plugins or Themes page before installing a different version. Some themes like bundled ones (e.g., twentytwenty) may have limited version history.
