I can't make a new gallery, I select the files, upload and then it disappears

I have 26 galleries, and when I went to make the next one, I was able to name the gallery, but after I selected (and it was wierd, since it wouldn’t let me select a batch at once) the ones I wanted and pushed Upload, after a few minutes everything went away and the screen for me to start from scratch was all that remained, with no sign of the photos I just uploaded, or tried to upload.
