Related Products Error Message

Hi there,

I’m getting an error message above my Related Product images when viewing a Single Product (Can be seen on the attached link) (Warning: Implode () Invalid Arguments Passed….)

Following is the line that the error message is referring to:

<div <?php echo implode(‘ ‘, $post_inner_attributes); ?> class=”<?php echo esc_attr($post_inner_class); ?>”>

Any help would be greatly appreciated.

Thank you,
Ainslee
