Hi,
 
I have multi site. they are on the same domain one handles retail the other wholesale.
 
If I go to one site place an order no problem
 
I then (close browser)visit the other site to place order and can do everything except submit the final page after filling in address details etc.
 
I delete cookies close and re-open browser and then I CAN place an order.
 
I have different session prefixes in var_definition.php
 
I simply cannot understand why this happening
 
I also have the following .htaccess file added
for each site.
 
php_value session.referer_check none
php_value session.use_cookies 1
php_value session.cookie_lifetime 315560
php_value session.gc_maxlifetime 1440
 
Regards,
 
Dave
