hi. no replys to my first post, so i'm bumping this again. hoping that someone else has seen this fatal error before & knows what we need to do to fix it. librarian changed the system preference for "AllowRenewalLimitOverride" (under Circulation) & now we can't access any Circulation parameters. when clicking on "Circulation" (under System Preferences) we get this message: Koha error The following fatal error has occurred: The given value does not seem to be interpretable as a Boolean value at /home/express/kohaclone/C4/Boolean.pm line 102.Apache Server version: Apache/2.2.3 Server built: Sep 8 2008 08:59:32 Koha 3.00.02.012 Koha DB 3.0002012 MySQL mysql Ver 14.12 Distrib 5.0.32, for pc-linux-gnu (x86_64) using readline 5.2 OS Linux shin.ec2.liblime.com 2.6.21.7-2.fc8xen #1 SMP Fri Feb 15 12:34:28 EST 2008 x86_64 Perl 5.008008 anyone have any ideas? i would really appreciate any help! -ss shane skeens ceo, senior strategist indigospin : media+marketing 806.438.3021 www.indigospin.com
