# User Register Notification Causes Session Issues

 * We use the civicrm plugin for our event registrations. When anonymous user fill
   pit the registration form and want to click the final register button in the 
   background the user signup is also performed simultaneously. Nevertheless, the
   event booking confirmation page afterwards is not loading, because the session
   of the user expired. The user will receive HTTP 500.
 * After deactivating the custom user register email the this does not happen anymore
   and booking confirmation page is loading smoothly.
 * Also, when activating the cron background settings of the plugin, everything 
   is fine again.
 * Nevertheless, we would like to send out the user registration email immediately
   and do not want to wait for the next cron interval. Can anyone help on this issue?
 * For reference: I already posted this issue in the civicrm stackexchange: [https://civicrm.stackexchange.com/questions/50036/event-signup-fails-for-anonymous-user-with-simultaneous-wp-account-creation](https://civicrm.stackexchange.com/questions/50036/event-signup-fails-for-anonymous-user-with-simultaneous-wp-account-creation).
   But it turned out it is not a pure civicrm issue… Nevermind, maybe there are 
   further relevant details.

 * Hey, thanks for reaching out!
 * Probably there are indeed some conflicts between the plugins and this is exactly
   the reason why we introduced the background processing. We’re always advising
   using it and using server scheduler to avoid any longer delays.
