I now have version 2.0.4 and still get the exact same error message listed by karlingersoll when posting a new sermon. When I look at the list of sermons, this error is listed in the Date Preached column:
Warning: date() expects parameter 2 to be long, string given in /home/content/c/o/c/cocwestside/html/wp-content/plugins/sermon-manager-for-wordpress/includes/template-tags.php on line 217
I have disabled the plugin while waiting for a fix. Thanks.
