Well, not entirely sure about this, but as a first check, please disable all plugins and see if the errors are still occurring?
Also, what WP version are you running?
Version 2.3.3
I can try disabling plugins but it seems somewhat a random error as haven’t installed anything extra for a while…
everything else on the site seems to be working fine…just the visual editor.
Although I am getting the following on the dashboard….
Error: jQuery is not defined

I’ve had some problems with losing the visual editor in the past.
Recently I caused this issue by using wp_enqueue_script in my functions.php file.
I see you have a few extra bits of javascript being loaded at the moment on your main site – if these are being enqueued then they could cause a conflict in the admin area with prototype or something (I know very little about this by the way)…
You have the following extra scripts running at the front end:
<script src="http://www.the-dish.co.uk/Scripts/AC_RunActiveContent.js" type="text/javascript"></script>
<script type="text/javascript" charset="utf-8" src="http://w.sharethis.com/widget/?wp=2.3.3&publisher=a6d22ebe-91ec-4f06-bce4-816b7dbd5a0a"></script>
<script type='text/javascript' src='http://www.the-dish.co.uk/wp-includes/js/tw-sack.js?ver=1.6.1'></script>
<script type='text/javascript' src='http://www.the-dish.co.uk/wp-content/plugins/useronline/useronline-js.php?ver=2.20'></script>
I don’t know if one of them could be causing a problem?!
