Installation Issues

Hi, I installed the plugin in WP 3.2.1, and started seeing the error message on top of the pages in the Wordpress Admin Area:

Warning: session_start() [function.session-start]: open(/tmp/sess_7d2eac122ed68bf1a96688de20e4a935, O_RDWR) failed: Permission denied (13) in /home/sareec/public_html/wp-content/plugins/comments-plus/lib/class_wdcp_model.php on line 44

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/sareec/public_html/wp-content/plugins/comments-plus/lib/class_wdcp_model.php:44) in /home/sareec/public_html/wp-content/plugins/comments-plus/lib/class_wdcp_model.php on line 44

I managed to go to the Settings and I then entered the info. Tried to save the info and I get a blank page with the error below:
