Hi,
I have upgraded to CB 1.2 on my testing site. It is running Joomla 1.5.8.
When you try register the user gets this error:
"Session expired or cookies are not enabled in your browser. Please press "reload page" in your browser, and enable cookies in your browser. Please refresh/reload page before filling-in."

I have determined that if I turn off Sh404sef (1.0.16_Beta Jan 2, 2009) then this message goes away and the users can register.

In my sh404sef configuration, on the By Component tab, I have choosen skip in the first column for comprofiler.

Does the sh404sef need to be updated for the new cb1.2? or is something going wrong in cb1.2?

First, you might want to upgrade Joomla to 1.5.9... a security fix for a Joomla problem found by CB Developers.

CB 1.2 is SEF compliant, meaning it adheres to the requirements set for Joomla core SEF... the same requirements any 3PD SEF component must adhere to. I noticed in the SH404 forums that they were waiting for a 1.2 download to become available to look at. You may want to give them a heads-up... it's here.
