I'm using the alternate version [hellsatan].
The percentage of posts and average posts per day are showing as zero to me. It may be a server issue, amykhar made a fix in the below thread for your similar hack - maybe this is of some use to you... It was to do with the way php handles the maths, and how slighlty different queries are required to function correctly on all servers.

I also request, if what Beermonster says is true, that permissions support be added. Although I suspect this may be an RC1 issue, as I've had some post counting problems myself.
