hi Thank you again for your help ,
I have just spoken with my hosting tech advisors today and they seem to think it could possibly be a request (of which you quite rightly point out) that may not be
supported on their server as they have updated their Linux servers from 3 years ago when I had no problem with the service , they are asking me to find out
what the request is though before making a definite diagnosis, I have tried the degugging but nothing shows up ;(
kind regards
Mike
