Hello, and sorry for the delayed response to your question. I took a look on your account and don't see any of your websites having any of the ExpiresByType commands in any of the .htaccess files that is mentioned in the Apache mod_expires article. It also looks like none of the WordPress sites you have are currently using the W3 Total Cache plugin. Hopefully you got things figured out. If you still had any other questions at all, please let us know! - Jacob
