FooGallery Caption Display error

Hi,

Up until recently the captions in my FooGallery galleries have been displaying as expected. But within the last few days something has changed so that they no longer appear. The images now have no captions.

Any advice would be appreciated.

Using Simple Gallery in FooGallery.
