@wrang: it sounds like you may have missed an install step or FTPed into the wrong place. Go through the install again, and this time when done, call the following from your browser so to be sure it happens:
Code:
admincp/index.php?do=buildbitfields
@Allan: discard old versions and only follow the current readme, so unless you uninstall product-photoplog.xml (which you should not do unless you want to lose information) you won't lose anything on upgrade.
