WP Safer Cache

There was a vulnerability in WordPress installations that used WP Super Cache prior to version 1.3 or W3 Total Cache prior to version 0.9.2.9. This helper plugin was a stopgap solution for older versions. If you have upgraded WP Super Cache or W3 Total Cache, you can safely deactivate and remove this plugin. I've posted a "post mortem" of the vulnerability (reasons, fixes, timeline, ...) on my blog. I will request this plugin to be removed from the wordpress.org plugin repository before the end of April.

Just install form your WordPress "Plugins|Add New" screen and all will be well. Manual installation is very straightforward:

1. Upload the zip-file and unzip it in the /wp-content/plugins/ directory
2. Activate the plugin through the 'Plugins' menu in WordPress
