DB Cache Reloaded

The fastest cache engine for WordPress, that produces cache of database queries with easy configuration - now with bugs fixed.


  • Make plugin compatible with WordPress 3.0 (single site mode; multisite mode requires additional work);
  • Added Dutch translation (thanks Rene);
  • Added Turkish translation (thanks wolkanca);
  • Added Japanese translation (thanks wokamoto);
  • Added German translation (thanks Carsten Tauber);
  • Do not cache queries which use RAND();
  • Fixed table filter not working all times (thanks poer for pointing this);
  • Code cleanup


  • Merged last WP 2.9 changes: bump required MySQL version to 4.1.2 for WP 2.9;
  • Added Spanish translation (thanks Dasumo)


  • Fix: WordPress plugin repository does not add hidden (.name) files to release archives - added workaround


  • Merged changes introduced in WordPress 2.9 (make sure you upgrade DB Cache Reloaded to version 2.0 before upgrading WordPress to version 2.9 - earlier plugin versions are not compatible with WP 2.9!);
  • Marked plugin as compatible with WP 2.9;
  • Added Wrapper Mode - with it DB Cache Reloaded can work with some incompatible plugins, like WP Tuner;
  • Added Belorussian translation (thanks FatCow);
  • Fix: added missing .htaccess file;
  • Fix: remove created files if plugin cannot be activated successfully


  • Marked as compatible with WP 2.8.5


  • Added Portuguese Brazilian translation (thanks Calebe Aires)


  • Show -1 as cached queries count when plugin's DB Module is not in use (e.g. because of conflict with other plugin);
  • Added check if DB Module version is in sync with plugin version (may not be if someone will upgrade plugin manually without deactivating it or disabling cache);
  • Allow to use DBCR_CACHE_DIR define to change default cache directory;
  • Fix: uninstall function was not executed


  • Further performance improvement;
  • Fix: changes done in admin section were not visible in frontend;
  • Added icon to use by Ozh' Admin Drop Down Menu plugin


  • Fix: queries were not cached starting from first not cached query;
  • Fix: all queries were cached in the same directory instead of dedicated subdirectories;
  • Fix: total row count calculation did not work for complex queries (usually observed as no pagination problem);
  • Added support for DBCR_SAVEQUERIES define to enable extended query logging (as compared to default SAVEQUERIES support)


  • Added Polish translation;
  • Added Italian translation (thanks Iacopo);
  • Show error in admin section when wpdb class already exists (this should not happen, but I got few reports about this);
  • Fix: do not cause fatal error when plugin is deleted manually without deactivating it first (in this case wp-content/db.php is left). Instead display error in admin section;
  • Added support for custom plugin directory;
  • Some performance improvements;
  • Show message in admin section when plugin is activated but caching is not enabled


  • Fix: statistics are not working


  • Took DB Cache 0.6 as a baseline;
  • Merged changes done in WordPress 2.9 for the wpdb class (this fixes annoying tags bug);
  • Cleaned up code, moved almost everything from global scope to class;
  • Secured settings page with nonces;
  • Switched to po/mo files for internationalisation
