Apache modules not found on Lite Speed server

Is anyone else getting an error message about missing the mod_mime, mod_headers, and mod_expires modules when using mod_rewrite on a Lite Speed server? I’m using Stable Host and they assure me these modules are installed and active. I’ve uninstalled and reinstalled Super Cache and deleted and recreated the .htaccess file but the message persists. The sites appear to be working normally. http://conservativearkansas.org and http://expensereimbursementissue.com .
