Introduction
Version 4.0.0 of Advanced Database Cleaner marks a major evolution of the plugin. Internally, the architecture was rebuilt to be more modular, more stable, and easier to extend. Externally, the entire interface has been redesigned with a smoother, more modern, and fully responsive UI/UX that allows you to work faster and more comfortably without the constant page reloads of the old version.
In this article, we walk through every module of the plugin – in the same order as the menu – and highlight what’s new in version 4.0.0 and, where applicable, what has been improved compared to the old version.
Every module also has (or will have) its own dedicated page with a video and a detailed article.
1. General Cleanup
General Cleanup remains the central place to detect unnecessary data in your WordPress installation and clean it safely. In 4.0.0, it supports more cleanup types, more control, and better visibility.
🔹 What’s new in version 4.0.0
New cleanup types
You can now clean the following additional items:
- Duplicated user meta
- Duplicated term meta
- Duplicated post meta
- Duplicated comment meta
- oEmbed caches
- Action Scheduler – Completed actions
- Action Scheduler – Failed actions
- Action Scheduler – Canceled actions
- Action Scheduler – Completed logs
- Action Scheduler – Failed logs
- Action Scheduler – Canceled logs
- Action Scheduler – Orphan logs
New “Keep last X items” rule
- Old version → “Keep last X days” only
- New version → also supports “keep last X items”
- Per parent (e.g. keep 5 revisions per post)
- Or globally (e.g. keep 5 pingbacks in total)
Estimated size to clean
You now see how much database space each cleanup type occupies, plus the total space that will be freed when cleaning.
Sorting in preview
Sorting inside the preview table (by name, date, size, etc.) is new – it didn’t exist in the old version.
🔹 What’s improved compared to the old version
- More advanced filters in preview
Old version had basic filtering; now, filters are richer and more contextual (by title/value, size, site on multisite, and more). - Deeper, standards-based cleaning
The old version relied heavily on raw SQL deletions. In 4.0.0, cleanup now uses WordPress’ native deletion functions whenever possible, ensuring full hook execution and deep removal of related data. Only when a core function cannot be used does the system safely fall back to the legacy SQL method. - Safer multisite handling
Old version could hit a few edge cases when deleting across networks.
Version 4.0.0 improves site targeting, deletion safety, and separation between network/site-level data.
