 * Hi,
 * I uploaded the plugin fine, but when I try to activate it, I get this message
   displayed at the top of my dashboard :
 * Warning: session_start() [function.session-start]: open(/home/content/57/11937857/
   tmp/sess_r3ufqtmf80i0gf70svabc7njs6, O_RDWR) failed: No such file or directory(
   2) in /home/content/57/11937857/html/wp-content/plugins/wordpress-simple-paypal-
   shopping-cart/wp_shopping_cart.php on line 12
 * Warning: session_start() [function.session-start]: Cannot send session cache 
   limiter – headers already sent (output started at /home/content/57/11937857/html/
   wp-content/plugins/wordpress-simple-paypal-shopping-cart/wp_shopping_cart.php:
   12) in /home/content/57/11937857/html/wp-content/plugins/wordpress-simple-paypal-
   shopping-cart/wp_shopping_cart.php on line 12
 * And none of the plugin functions work!
 * Could you please tell me what’s wrong? Could there be a conflict with the Responsive
   pro theme I use? What can I do to solve this problem?
 * Thanks a lot for your answer,
 * Ipso Imago
