Hi Guys
I'm getting a similar issue here.

I can log into FOP2 fine - using Firefox11.
However a collegue using Chome, cannot.
He types:
xxx.xxx.xxx.xxx/fop2
and the page automatically redirects to
https://xxx.xxx.xxx.xxx/fop2/
And shows him "Invalid Session" in the page.

Here's the thing though. Mind is a fresh new install of Elastix 2.3.0-6 and I installed FOP2 from the addons page. Then Revoked my old registration code from my old Trixbox, and registered it on the new Elastix box.

So in theory, there's no upgrading been going on at all.

Help.....

Cliff.
