The following fatal error is shown when trying to sort the albums when logged in as admin:

Fatal error: Call to a member function setSortDirection() on a non-object in /home/[USERNAME]/public_html/[ZENPHOTO-GALLERY-DIRECTORY]/zp-core/admin-edit.php on line 70

I tried on galleries installed via 1-click "QuickInstall" as well as manually by FTP upload and using the setup.php as required to qualify for support in this forum (Yes I read the Terms and Conditions before registering )

The hosting is on Hostgator Business host. The PHP version installed is 5.3 and the MySQL version, although not the preferred 5.5.0 (since upgrading to it is beyond my control) is 5.1.56

I am aware this comment may not be visible initially since I am a new user here, but I'd sure appreciate if anyone could point me in the right direction, even it that's only stating that the behavior is a known bug in need to be fixed in later versions of ZenPhoto.

Thanks!

It appears you have found a bug. This will be fixed in the nightly build after tonight.

I downloaded and installed the gallery today, but I'm still getting this error when trying to sort my albums.
When will this bug be fixed?

Try the trunk nightly build.

Thanks, that solved the problem!
