For a while now some collections exhibited a strange behavior when trying to download. After pressing the Download button, the screen would blank and then come back to the download screen. The download never happened.
I did an svn update today and among the new files were:
/pages/download.php
/pages/collection_download.php
I tried the problematic collection again and got an error suggesting that the download would be too large. True, it would have been 7.8Gb. Choosing fewer files allowed a successful download.
Thanks ResourceSpace.
