image Gallery Caption

Hi

There seems to be a problem with captions on the image galleries.

they appear as an empty box without the text in them.

Or if you don’t set a caption you still get the empty white box appear over the image.

any ideas on how to fix this, either don’t show the empty caption box or show the caption if used.

It does not do this on the featured picture so you have to scroll to the next picture and hover on the image for the box to appear.

Need to fix this somehow as it looks un-professional..

Thanks
