Missing widget title

Hi Michael,

Love your plugin, but my site unfortunately got a problem after updating to 2.16.3.

The widget titles which link to a testimonials page no longer show up. Instead of a title it only says ARRAY.

My site is http://klartilkina.dk

I use the testimonials widget on the home page and in different sidebars.

Thank you in advance for any advice on what to do.
