EFSEO error message when used with Jreviews

Hi,

I recently installed EFSEO - Joomla 1.5, on my website, that uses a listings component called Jreviews.

When I try to add a listing as one of my users would, I get the following error message:

Notice: Undefined offset: 0 in /home/happy019/public_html/plugins/system/easyfrontendseo.php on line 519

This error does not look good especially when a user is trying to add a paid listing.

Do you know why this is happening and how I can stop this error from displaying.

Thanks,

Jason
