PHP Loop Issue

If you look at the attached screen shot, I have an issue that I can't figure out how to resolve. It was working and then now we are unable to edit the home page. It goes into an infinite loop within the editor, not the viewing of the home page. Here is part of the code... array( 'name' => 'box-testimonials-colunm', 'label'=> 'Colunms', 'layout' =>'table', 'min_rows' => 3, 'max_rows' => 3, 'type' => 'repeater', 'controls' =>array( array( 'name' => 'box-testimonials-details', 'label'=> 'Details', 'type' => 'repeater', 'layout' =>'row', 'controls' =>array( array( 'name' =>'box-testimonials-details-name', 'label' =>'Name', 'type' =>'text' ), array( 'name' =>'box-testimonials-details-description', 'label' =>'Description', 'type' =>'text' ), array( 'name' =>'box-testimonials-details-content', 'label' =>'Content', 'type' =>'textarea' ) ) ) ) ) .... We need help resolving this issue .
