Plugin Interferes with featured image WP 3.6

I’m using Responsive Child theme and wordpress 3.6.

For some reason my featured image has been spaced downwards upon the update to 3.6. I deactivated all the plugins one by one and the problem went away when I deactivated “Linkable Title Html and Php Widget by PepLamb”.

No idea what’s causing it but I’d love some assistance.
