Mantra Theme From QuemaLabs functions/option_panel.php Error


Does anyone have the solutions to a themes/mantratheme/framework/functions/option_panel.php on line 248 error message when using the Mantra Theme From QuemaLabs?

When we disable the theme and replace with another the error goes away so know it is theme related.

There are not updates listed for the theme since 10/2013.

Thanks in advance for any help you can provide to us!
