Uploaded files are not updated :x

Sometimes, when I upload a file either via SmartFTP or explorer, the file shows up on the server, but the older version still appears at the website.

Deleting files, refreshing, restarting does not help, and the same old version appears on other computers too, while the newer appears on the FTP.

Even DELETING the file from the FTP, doesn't help. the change is updated only a few hours later (although sometimes entering an address without the www magically shows the new file)

can anyone help? I'm going mad here...

Ok, this is a common problem that can be caused by several issues:

a) your hosting provider have a problem with the server, contact the admin
you have a problem with your ie cache, and the way is to clean the cache and see if you see the updated file

hope this help.
