I have a Pragma Problem

Sorry by posting this again but since i dont know in which section to write here it goes:

Hi. Ive been noticing that google doesnt crawl my site like it used to, and while checking the http server headers i found that my site is diffrent from the other wordpress blogs i run on the same server.

here it goes what i see:

Response Code: HTTP/1.1 200
Date: Wed, 30 Apr 2008 08:25:36 GMT
Server: Apache/2.2.8 (Unix) mod_ssl/2.2.8 OpenSSL/0.9.8b mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 PHP/5.2.5

Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0
Pragma: no-cache

The other sites dont have the cach-control not the Pragma.
This is making google not to cache my site. I tried to update the wordpress and the problem presisits.

I also found that this might be related to a plugin called Crawl Rate Tracker as THIS Page says it has the same problem. I unnistalled and same problem.

I also think it could have been generated while i tried WP Super Cache.

Do you know any WordPress core file i can reupload so i can have it back to normal without the Cache Control And Pragma?

Please this is really urgent. Thanks 🙂
