 * Hi there,
 * Sessions are how Give is able to recognize unique donors on your site, so that
   when they finalize their donation, they see their own donation receipt and not
   someone elses. Your site seems to be having some trouble with sessions. There’s
   a few things I’d suggest trying to get around this issue:
 * 1) Install this plugin that will force your site to use native PHP sessions, 
   instead of WordPress sessions: [https://wordpress.org/plugins/wp-native-php-sessions/](https://wordpress.org/plugins/wp-native-php-sessions/)
   
   2) Add this to your wp-config.php file: `define( 'GIVE_USE_PHP_SESSIONS' , false);`
 * Note, don’t use BOTH of these — they contract each other. Try one (clear all 
   caching if you have caching), and if the first doesn’t work, disable it then 
   try the next one.
 * Thanks!
