The tag cloud is a nice widget in my sidebar, offering a way in to my pictures. As of recently things have changed. Once I click on an item, it shows a series of thumbnails from page 1 of the image series. So far so good.
However, pages 2 and up do not show at all. A blank page is the result. This goes for all tags in the cloud, but there is no problem showing ordinary galleries page by page.
What is the cause of this?
