The script is set up to run from the phpbb root now. I think it should be set up to run in the admin folder.
it shoulden't really matter where the file is located, if however the file was located in the admin folder, it whould be posible to have a link automaticly added to the admin panel, but then again admin panel would take longer to load, it is more a matter of "style" where the file is located.
I guess this file will not be used so offen (maybe only once a year), I have choisen to place it in the root, and not include it in the admin panel - therby sloving the load of this page...simply call the URL instead it is simple and fast
btw. try and explain the problem with the topic/posts count, I haven't notised any problems...
