Chris,

Thanks very much for your reply.

I have just tried that and it hasn't worked. It's as if the fault is within the 'global.php' file but obviously it isn't as it works fine under normal conditions.

I am sure that the error is very simple but I just do not know enough to be able to see it.

The only change I have made to the code since being sent it by another VB user is that I changed the directory url to obviously match the directories on my site rather than his. There aren't errors there though or it would not be able to access the 'global.php' file.

Being ignorant is unusually frustrating.
