Petko -
thanks very much -

there were no definitions of $PubDirUrl or $FarmPubDirUr in my config.php,
so I defined them as you suggested.

I also needed to define $ScriptUrl (which for some reason doesn't point to
the scripts folder - so I took a wrong turn there!)

Everything seems to work fine now.

Thanks again
James
