Cache Actions

This section provides quick administrative actions for managing cache and plugin settings.

Clear All Caches

Clears all cache types managed by DJIA Cache.

This includes:

  • page cache
  • asset cache
  • object cache
  • generated optimization files

Use this option when:

  • updating themes or plugins
  • modifying styles or scripts
  • troubleshooting caching issues

Run Cache Tests

Executes diagnostic tests to verify that DJIA Cache is functioning correctly.

The test checks items such as:

  • cache write permissions
  • cache directory accessibility
  • drop-in availability
  • caching behavior

Restore Defaults

Restores all DJIA Cache configuration settings to their default values.

⚠ Warning:
This action resets all plugin settings and cannot be undone.

Cache Tools

Provides quick actions for clearing specific cache types.

Purge cache (ALL)

Immediately removes all HTML page cache files.

This forces DJIA Cache to regenerate fresh cache when pages are next visited.

Purge current URL

Clears the cache for the currently viewed page or URL only.

This is useful when:

  • editing a specific page or post
  • testing layout or style changes
  • debugging page-specific issues

Cache Preload

Allows administrators to manually generate cache before visitors access the site.

Run Cache Preload

Starts the cache preload process.

DJIA Cache will:

  1. read URLs from the configured sitemap
  2. request each page
  3. generate cached HTML versions

Benefits:

  • faster first visitor load
  • warm cache after purge
  • improved performance consistency

Database Maintenance

Provides tools for cleaning and optimizing the WordPress database.

Run Database Cleanup

Deletes unnecessary database data such as:

  • post revisions
  • trashed posts
  • expired transients

⚠ Warning:
This operation is irreversible and permanently removes these items.

Optimize Database Tables

Runs optimization queries on WordPress database tables.

This helps:

  • reduce table fragmentation
  • improve database performance
  • reclaim unused storage space

⚠ Warning:
Table optimization may take longer on websites with large databases.

Cache Statistics

Displays information about current cache usage.

Page Cache Statistics

Shows a breakdown of the page cache directory, including:

  • number of cached files
  • total storage size used
  • cache directory location

This helps administrators monitor how much disk space the cache is consuming.
