Credit to @bsmither not me. I'll demote myself to tea boy. 

Infact it's 6pm so lets say "Beer Boy".  

Cheers!

"Manually set to:"

$cookie_domain = '.sitename.co.uk';
                        ini_set('session.cookie_domain',$cookie_domain);

I suggest restoring that code in session.class.php to its original:

		$cookie_domain = $GLOBALS['config']->get('config', 'cookie_domain');
		if(!empty($cookie_domain) && strstr($GLOBALS['storeURL'],ltrim($cookie_domain,'.'))) {
			ini_set('session.cookie_domain',$cookie_domain);
		}

I understand that at times it is necessary to override what CubeCart automatically determines what the most appropriate value should be.

Also know that almost all $GLOBALS['config'] keys/values can be created and overridden in the /includes/global.inc.php file. For example, on a localhost development machine, I have:

$glob['cookie_domain'] = '127.0.0.1';

among other necessary overrides.

No doubt a contributing factor was the security setting of the web browser -- domain mismatch equals no cookie sent. Which is not a bad thing!

I am still concerned about why the GUI instantiation got lost.

Looks like I was too quick to mark this as resolved. Will remove it for now.

If the OP says all is good, then that's it.
