Because the staff is very small and not very knowledgeable.
The solution to this is to employ more knowledgeable staff. If money is a problem, maybe stop paying people to spam the forum with signature ads and use the money saved to pay for competent support staff. There's little point advertising the site when it isn't ready to handle increased traffic yet. New people will visit, be disappointed by all the broken stuff and lack of support, and not stick around. Better to focus on fixing things first, and then bringing in players later.
