Problem with Ministry tab

Hi! I hope I am posting this in the right place. First, I would like to say how wonderful this plug in is.

But I am having some issues with the ministry tab. I can’t add a ministry. I keep getting the following error:

Warning: _() expects exactly 1 parameter, 2 given in /home4/sjm/public_html/wp-content/plugins/church-admin/includes/departments.php on line 170

I don’t know my php well at all and was wondering what I need to do to fix this problem.

Thanks for all your hard work to help all of us ministering to the Body.

Deborah
