Cb registration cookies

Hello, I want your help because I have a problem when I submit a new registration I have this popup : Session expired or cookies are not enabled in your browser. Please press "reload page" in your browser, and enable cookies in your browser......
I have try to purge the cache at joomla administrator and to ennable cache but nothing, And I have update cb

Disable all caching, purge the cache, then retry. This is almost always a caching problem. If caching is already completely off then see if you've any 3rd party Joomla system plugins within Extensions > Plugins and try disabling them to see if that solves it. Aside from that please search the forums as this has been addressed numerous times.

Thx....I have try to do Rhiz but nothing...can u help me please because I have try all solutions found in forums

I Have the same issue, 2 mounth of search of solution, i tried all, not work.

thnks

It's either a caching problem or a cross domain problem as already explained. See my above reply for solutions. First step is to disable all caching then purge the cache. If issue persists ensure configuration.php is configured properly (live_site should be set to ''). If configuration.php is configured properly reset your htaccess file by either deleting it or reapplying the one provided by Joomla. Those steps should eliminate those issues. If issue persists still then it's likely some sort of session problem caused by a server configuration issue or 3rd party extension conflict.
