Mostly members are complained about this issue & site slow response.
Can you point me to a page where you see this? Have you contacted our support team?
Message show on random page not on a specific page at www.vustudents.net . No I have not sent any ticket to support team. one more thing my members always complaint me about site slow response & browser crash/hang PC complaint when they visit the site.
Do you have any third-party Flash or Silverlight content on your network? That's my best guess. It's really hard to say what is causing this, but I have seen it before myself on different types of sites. Here's some info about how it might happen. It's not really specific to Ning.
I noted that when me & my members use the new chat then this message show.. if I & my members use the site with offline chat status then site mostly working fine. After new chat a lot of members complaining about this matter.
