The more important question is why there is a Java popup on your website?
The intention was to display a warning to users who have Java installed however the detection code is causing problems because navigator.javaEnabled() returns false positives and the Oracle detection code is trying load an applet. The changes have been reverted now.
Nope. Its still saying i need to disable java (red alert on the right). Then when disabled, no input boxes to login.
