I have a 2860n, and the Lan >>Web Portal Table is blank, See image. Can anyone suggest how to fix it.

The Firmware version is 3.8.2_VT2

Me too:
2760n f/w 3.8.1_VT2
It was there, I filled in one profile (but not enabled), saved.. was asked to reboot, did so, now see empty table...
TIA.

@sparx... did you fix your issue?

Just tried this on my 2925 and I wasn't even asked to reboot.... (setting one up for Guest Wifi) and it worked. Granted the firmware base is a bit different on the 2925, I'm running 3.8.2_RC4
