I updated my file by using ftp. (The file manager is off-line) I have checked the content of the updated file on the ftp server: it is successfully updated. But when I go to my website, the page that I updated by using ftp is still not updated. I tried refresh that page many times, viewed it from another browser and another machine. The result is the same. What is the cause of this problem? How can I fixed it?

Hello Dshirew,
It may be that your browsers "Cache" may be preventing an update of the information to you... Have you tried deleting your browsers cache?

Hope this helps you out.

Hi zpcs,
Thanks for your suggestion. I have tried deleting my browsers cache. But my webpage is still not changed.
