I posted over at woltlab about the graphic issues, and the following error message appears when you visit the site. I have had this 4 times when upgrading my own instillation of woltlab, at RC2 this should not be an issue. It really is making me nervous now i have submitted my recommendation to use woltlab across all our sites. I understand the rush to get software out, but i can assure you that the current pace is putting people off what would be a great product with a little care and less speed. It wont matter for the first year, as there is free support, but are people expected to buy support every year just to correct software bugs?
