Yeah, the version on my site is the vb3 version; its got a lot more features implemented in it as i've been developing it longer; with the advent of vb4 changing all the style stuff, i've had to reimplement the entire user interface.
A good portion of the interface is done and will be in the next release; feel free to copy the instructions from my site in the interim thou. There are also some faq entries, but these will be out of date as since i've had to reimplement the user interface, i'm improved it quite a bit as well.
For the db error, find the get ALL posts plugin (from the pbpg core) find this line:
PHP Code:
$perpage = 99999999999999999; //should be enough...
change to:
PHP Code:
$perpage = 99999999; //should be enough...
This will be fixed in the next pbpg core release.
