Have many albums without any prior problems. Latest version etc etc.. Now one of my albums refuses to show thumbnails. The gallery level album picture chooses one at random without issue, and if i search for the image filename explictly I can see it, but the array of thumbnails will not display. This is happening for just one album that is no different from any other (same camera etc) and used to display fine. It is published. I've even looked through MySql tables to see if anything is corrupted... looks ok.

So what do you see instead of the thumbnails? Best to provide a link.

I see the following text on a blank page.. also the search text field on over the top of the word Gallery in the top left. There are no thumnails, no links to anything... just the following..
