Batch page doesn't work

[Tano*87]

Hi there...Yesterday I've upgraded my coppermine gallery and now I was trying to add pictures and actually I can use the batch page ONLY with the coppermine themes. I tried to batch with my own default theme, the one that I used before the upgrade and actually the "select/deselect all" botton doesn't work, same for the botton that starts the batch.

What can I do for it? How can I fix it?
