Warning: Invalid argument supplied for foreach()

Hi there!

I installed the Profile Completeness and I got these warnings:

Warning: Invalid argument supplied for foreach() in /home2/mysite/public_html/modules/mod_js_pro_complete/mod_js_pro_complete.php on line 39

Warning: Invalid argument supplied for foreach() in /home2/mysite/public_html/modules/mod_js_pro_complete/mod_js_pro_complete.php on line 48

Warning: Division by zero in /home2/mysite/public_html/modules/mod_js_pro_complete/mod_js_pro_complete.php on line 53

I'm a newbie in PHP. Can you help me to fix it?

Thanks
