I installed this last night, and got the same initial problem.
First off, I relaised that I hadn’t put my del.icio.us username into the code where it calls the script… so I fixed that (duh).
Still only got the ‘1’ result though, but it turned out that it just needed to be left alone for a while – the script (once it’s been called the first time) goes off and caches your del.icio.s links every half hour or so – until it caches for the first time, you’ll just get a ‘1’.
