Installed but I'm experiencing an error. For some reason the lightbox shows any images starting from 22 instead of 1. For example in the attached thumb it shows 3 images in a test gallery but identifies them as images 22, 23 and 24 of 26 images. There are no images between 1 and 21 and 25 to 26.
This error occurs on any gallery, no matter how many images are included. Its always first 21 blank and 2 blank after the last image. Any idea why this may be?
