Nice plugin

I have downloaded and install it. Very nice plugin.

I am facing an error at plugin page
“Notice: Trying to get property of non-object in D:\wamp\www\plugin\wp-content\plugins\my-responsive-testimonial\index.php on line 133”

another error “D:\wamp\www\plugin\wp-content\plugins\my-responsive-testimonial\index.php on line 229” is facing at “add new post” page.

Please, fix these. Add an option panel with help page.

Thanks and best wishes
