para mi la solucion a este problema fue deshabilitar en el CB Configuration Manager - Integration - la opcion Enable anti-spoofing sessions checks.

I have same problem starting up with Joomla 1.6.3 and CB 1.4. At first the site ran fine then the sessions/cookie errors started on log in. I have disable cache, moved mod_cblogin to top of left column, etc. etc. I think I might too have to switch to the competition. I was just getting ready to take out the paid subscription, but I think I will wait to see if this issue can be solved quickly. Please help if you have an answer.

Having the same error here. J! 1.6.3 and CB 1.4. Site was running fine yesterday. Today I get this message:

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.

No reason this should be happening. Please please help. I have already upgraded to professional level

Ok, I found another thread (did not see it before I posted here)

Here is the link:

www.joomlapolis.com/forum/146-general/163019-session-expired-or-cookies-are-not-enabled-in-#165357

Basically you go to CB Configuration -> Integration tab -> set anti-spoofing checks to off.

Worked for me. However any insight to what security issues they may open up would be great.

Happy I am up and running again!

Work for me after 5hours searching in this forum... Otherwise for those who has problem of double url location after login in CB_login, just ensure that in local, your site url (local path) does content space between words provides. Ex. your local path is : c:\localhost\my web site\

it should be in this linux format : c\localhost\my_web_site\

delete all space between words in your path indeed. It work great !
