FTP'd the files for the update, got to the check and prompt for passwords but after entering them, nothing happens, the screen stays at the check page. No errors, nothing.

The URL I entered was http://mydomain.com/zen/zp-core/setup.php

which changed to http://mydomain.com/zen/zp-core/setup.php?mod_rewrite=ON

Used Safari instead of Firefox and managed to update. After GO was told two albums ID were changed from 2 to 3 and 9 respectively. These were two that I had questioned sorting in previous post but was never able to do anything after that (timewise). Next chance, will see if that's fixed.
