If you suspect the web site is displaying out-of-date information, please read on...
(if you would like further help with this, then please send an email to the address at the bottom of this page).

A quick check to see if the web page you are viewing is out-of-date is to press the Ctrl key and hold it down while you press the F5 key.  If the content changes this is an indication that your PC is not picking up the latest information.

Reasons for out-of-date information

When you surf the internet, web pages that you visit are saved on your PC in a temporary location (cache) to speed up access next time you visit those pages.  The PC checks if the page has been updated since your last visit; if so then it reloads the updated page from the internet, otherwise it uses the saved page.

Sometimes this checking mechanism goes wrong and your PC continues to use the saved out-of-date copy instead of the latest; this is a known problem and affects other web sites, not just this one. It may sort itself out after a few days, but it's not guaranteed.

The above Ctrl & F5 technique only forces a reload of the single page you are currently viewing, so a more convenient solution is to force a reload of all pages by deleting these 'temporary internet files'.  You can do this manually or automatically.

The actual method depends on the type and version of Internet browser you are using.
The following examples assume you are using Internet Explorer:-

Manual Solution

If you can see the Internet Explorer icon, right-click it, then left-click Properties
(if you can't see the icon, then click Start, (Settings), Control Panel, Internet Options)

Depending on the version of Internet Explorer, you should see an Internet Options/Properties window something like this:-

Click General at top-left, then click Delete; this will display a further window allowing you to select which items are to be deleted:-

If you don't see the above windows, try looking around for an option to Delete Temporary Internet Files; it may look like this:-

Either way, click Delete Files, then click Yes if asked to confirm.
The delete process can take several minutes so be patient.

More information from Microsoft can be found here, although it doesn't mention anything about the checking process not working properly!

As this is a manual process, you may need to repeat this at regular intervals; alternatively use the Automatic Solution below.

Automatic Solution

To avoid manually deleting these files on a regular basis, you can configure your browser to automatically delete them whenever you close it.  This is a reasonable compromise as it will then use the caching system during your session, but everything will be refreshed & brought up-to-date when you start your next session.
This may slow down your internet access to some degree, although broadband users so far have reported no difference (and some even found it was quicker!).  If you find it a problem with your system, then simply reverse the modification shown below.

To configure your system, display the Internet Options/Properties window as shown in the manual solution above, but this time click Advanced, then scroll down and look for a tick-box called 'Empty Temporary Internet Files folder when browser is closed':-

Click the box to 'tick' it, and then click OK.
When you close Internet Explorer for the first time, there may be a delay of several minutes while it deletes all the temporary files it has built up over time, but subsequent close-downs will be much quicker.
