shtml - [error occurred while processing this directive]

[cronic]

Help!
I've been using shtml for years now and its all good normally. Last night I noticed a spelling mistake on my home page so i went into dreamweaver; corrected the 1 letter mistake and uploaded the page.
When i checked the online version the server side include had broken down giving the following message:

[an error occurred while processing this directive]

The rest of the site still functions as normal (the web services pages are shtml tho some others are not yet).

I did a test with another page, one thats been online for ages without a problem, offline all i did was change the filename from audio.shtml to audio2.shtml; I uploaded this page and this too has the error.

So it seams any shtml I upload now is broken. Works fine offline, the SSI's have not changed. What could possibly cause this?

The site itself need a good tidy up so please ignor that, the offendin page is here:

One shtml page that still works is here:

Any ideas?
