Problem Updating a htm file

[#1]

I have a small family history website which I update from time to time.
Normally I make the change on my computer then FTP it to ftp.plus.net and the change works fine.
Yesterday when I ran the FTP it seemed to work OK but nothing seems to have changed in the live environment. i.e the index displayed the previous information.
It's a good few months since I last made a change to the index on my website.
Has anything changed recently? I have already dealt with the change of hosting site for CGI.

The index file in that particular directory has an update timestamp of this time yesterday. That suggests the newer file /was/ uploaded.
Have you tried forcing a cache reset (try holding CTRL and F5 on the keyboard when viewing the site).
Also, is the file listing intentional when you visit your website without pointing your browser to a particular folder? Just asking because it's fairly trivial to disable this behaviour.

Thank you Bob
CTRL and F5 did the trick.
I haven't had to do this before.

Hi Bob
I don't really understand what you mean about the file listing.
Can you please explain further, with perhaps an example

What this means is that when you browse to your website without specifying a file or folder name, ie enter only www.username.plus.com on the address line you are shown a list of files in that (top level) directory (the list might be empty)
When a file name is not given the default behaviour is for the server to look for a file called index.htm or index.html and serve that. Getting a directory listing implies you don't have such a file.
Adding a simple index.htm file would stop directory listing or, as Bob mentioned a special directive in a .htaccess file could be used to disable directory listing.

It's as David has explained really, e.g. I browse to your default webspace address and I see this in my web browser:

Let me know if you want this behaviour disabling.
