Blank screen when opening WebVPN/SSLVPN

[GemeenAapje]

Hi all,

I'm trying to get the WebVPN/SSL VPN working on an 1812W router, to no avail.

I have the WebVPN configured perfectly, using samples from Cisco.com and other parts of the net. It connects, asks to confirm the certificate, and then loads a blank white page. The HTML just shows a few tags like HTML and BODY etc, but there's nothing else. (See attachment)

What is my router missing (File on the flash drive?) that should produce the web page required?

I've uploaded all the files possible and it should be fine. Here's a list from my router...
sh flash
