Hi ColdSprit,

You’ll need to make sure that the W3 Total Cache plugin’s object caching and database caching are deactivated.

Along with that, you can increase the amount of memory available for WordPress by following this guide:
​http://codex.wordpress.org/Editing_wp-config.php#Increasing_memory_allocated_to_PHP
You can use an [FTP client][1] and [a text editor][2] to edit the site’s wp-config.php file:
[1]: http://codex.wordpress.org/FTP_Clients
[2]: http://codex.wordpress.org/Editing_Files#Acceptable_External_Editors

This will avoid potential errors with recording the registration data due to your server running low on memory.

Also, you can try the setting that encodes the registration session data. This can prevent fatal errors on some servers. It’s recommended to try this setting during off-peak registration times just in case your server doesn’t allow using base64encoding (some of the cheaper shared hosts don’t). You can set Event Espresso to encode session data by going to Event Espresso > General Settings > Admin Options and set Encode Session Data to Yes, then save. After you save this setting, it’s important to test a registration to make sure your server supports encoding data.
