Okay, I one by one turned off every hack I had and reverted all my templates, and still no birthdays. I then checked to make sure somebody was having a birthday, and it showed four in the calendar. Then I changed my birthday to today, and finally the birthdays displayed (all of them). There is a bug alright, but it looks like it is in vb itself having to do with the active users and birthday settings.

Edit:
It appears confirmed that there is a birthday bug in vb.

Well, as my forum is still closed to the public while I fiddle with everything, it's not a big deal, and thank you for looking into it. I'll keep an eye on this thread for whatever solution. ;)

This mod looks great - I installed it diring the middle of last month. Today's the first of the month and unfortunately it's just red arrows pointing down. I know why the arrows are pointing down but new visitors to my site probably won't realise why and it may put them off signing up. Is there anyway to disable the red arrows and only have green arrows show (when the stats are on the increase to show positive growth)?

Okay, the problem was that if there aren't any events or birthdays coming up, the box disappears. Problem solved.

vbTrends 2.0 is well underway, and it will address this issue. :)

Cool! - something nice to look forward to :) :)

A very preliminary screen shot of the chart designer for 2.0.0.

It's ajax - the preview chart reflects your changes in real time.

What would be great would be the ability maybe exclude a forum from these new stats - I use vbPortal and have a specified forum where the threads in that forum create the news stories for the front page of the portal.

You can. That's what the match box does. Here's an example:

Thanks :) How about clicking install?
