[Koha] Question About Koha Reports

Dear All, I have installed Koha 2.2.4 Library System on Gentoo Linux and everything work fine except some reports like borrowers reports and some other which just output zeros or empty tables though koha database has members and books and all fields are not empty. Is that a bug or just a configuration issue? Thanks for your time. --------------------------------- Yahoo! Mail Use Photomail to share photos without annoying attachments.
