Sorry we didn't respond yet. We went through your site with a fine-tooth comb the other day and made no progress in figuring out what possibly could be causing that! It seems like there's a hard-coded height on that module position, or one of the surrounding divs, but we couldn't ever find anything like that.
Can you try moving it into other module positions just to see if it ever works, or even create a 'custom HTML' module in that position with a lot of text and see if the same thing occurs to other modules?
Any investigation you can do like the above will greatly help us to figure out what's up.
Hey, it seems like you guys have at least got the invite module working part of the time, so maybe you can help me out.
I have the invite module working good (no sefs), and can send invitation just fine. However, when the users clicks the button to confirm, it always says "you have just ignored..." and nothing happens. Do you have any ideas on what to do?
