ctbrooklyn on "warning: mysql"

Across all pages of my site there are two rows of type along the top that read:
Warning: mysql_real_escape_string(): A link to the server could not be established in /home/wp_ygtcuz/quippyqueer.com/wp-content/plugins/subscribe-news-letter/subscribers.php on line 73
I updated everything, including my theme (Twenty Twelve). How can I eliminate this?
Many thanks!

That is an error coming from the Email subscriber plugin. Disable that plugin and see if the error goes away.

Thank you! That did it. Now do I need to add a new version of a subscriber?
