Revive Object-Cache in Wordpress 2.5
Users who have recently upgraded to Wordpress 2.5 might have noticed that the Wordpress object cache is disabled, or rather gone forever: define(‘ENABLE_CACHE’,true) no longer has any effect.
Apparently, Wordpress decided to ditch the file system based object-cache due to some compatibility issues. But for many high traffic bloggers, no cache = no blog. Neosmart has compiled a neat article here.
But not all hope is lost, Neosmart has also brought the cacher back from the dead!
For dedicated server users, its is very recommended that you use memory based caching in conjuction with a PHP opcode cache: APC, eAccelerator and XCache.
