หน้า Directly Cached Files มันขึ้นแจ้งเตือน

Warning! /home/thaizone/domains/xxxxxx.com/public_html/ is writable. Please make it readonly after your page is generated as this is a security risk.
Add direct page:
Directly cached files are files created directly off /home/thaizone/domains/xxxxx.com/public_html/ where your blog lives. This feature is only useful if you are expecting a major Digg or Slashdot level of traffic to one post or page.
For example: to cache
http://www.xxxxx.com/about/, 
you would enter
http://www.xxxxx.com/about/ 
or /about/. The cached file will be generated the next time an anonymous user visits that page.
Make the textbox blank to remove it from the list of direct pages and delete the cached file.
