Hello,

I'm getting this error in the forum:

Can't call method "parents" on an undefined value at /home/virtual/domain.com/var/www/cgi-bin/forum/admin/GForum/Category.pm line 136

I enabled debbugging and this is what I got:

A fatal error has occurred:

Can't call method "parents" on an undefined value at /home/virtual/domain.com/var/www/cgi-bin/forum/admin/GForum/Category.pm line 136.

Please enable debugging in setup for more details.Stack Trace======================================GForum (1705): GForum::Category::_full_name_cache called at /home/virtual/domain.com/var/www/cgi-bin/forum/admin/GForum/Category.pm line 89 with arguments (2).GForum (1705): GForum::Category::full_name called at /home/virtual/domain.com/var/www/cgi-bin/forum/admin/GForum/Forum.pm line 778 with arguments (2, : ).GForum (1705): GForum::Forum::_plg_normalize called at /home/virtual/domain.com/var/www/cgi-bin/forum/admin/GForum/Forum.pm line 764 with arguments (HASH(0x86040f4)).GForum (1705): GForum::Forum::__ANON__ called at /home/virtual/domain.com/var/www/cgi-bin/forum/admin/GT/Plugins.pm line 105 with arguments (HASH(0x86040f4)).GForum (1705): GT::Plugins::dispatch called at /home/virtual/domain.com/var/www/cgi-bin/forum/admin/GForum/Forum.pm line 764 with arguments (GT::Plugins, /home/virtual/domain.com/var/www/cgi-bin/forum/admin/Plugins/GForum, forum_normalize, CODE(0x8596660), HASH(0x86040f4)).GForum (1705): GForum::Forum::normalize called at /home/virtual/domain.com/var/www/cgi-bin/forum/admin/GForum/Forum.pm line 40 with arguments (HASH(0x86040f4)).GForum (1705): GForum::Forum::view_collapsed called at /home/virtual/domain.com/var/www/cgi-bin/forum/admin/GForum.pm line 292 with arguments (GForum::Forum, forum_view_collapsed, HASH(0x84304ec)).GForum (1705): GForum::_plg_do_func_2 called at /home/virtual/domain.com/var/www/cgi-bin/forum/admin/GForum.pm line 240 with arguments (forum_view_collapsed).GForum (1705): GForum::__ANON__ called at /home/virtual/domain.com/var/www/cgi-bin/forum/admin/GT/Plugins.pm line 105 with arguments (forum_view_collapsed).GForum (1705): GT::Plugins::dispatch called at /home/virtual/domain.com/var/www/cgi-bin/forum/admin/GForum.pm line 240 with arguments (GT::Plugins, /home/virtual/domain.com/var/www/cgi-bin/forum/admin/Plugins/GForum, do_forum_view_collapsed, CODE(0x8350bdc), forum_view_collapsed).GForum (1705): GForum::_plg_do_func called at /home/virtual/domain.com/var/www/cgi-bin/forum/admin/GForum.pm line 231 with arguments (forum_view_collapsed).GForum (1705): GForum::__ANON__ called at /home/virtual/domain.com/var/www/cgi-bin/forum/admin/GT/Plugins.pm line 105 with arguments (forum_view_collapsed).GForum (1705): GT::Plugins::dispatch called at /home/virtual/domain.com/var/www/cgi-bin/forum/admin/GForum.pm line 231 with arguments (GT::Plugins, /home/virtual/domain.com/var/www/cgi-bin/forum/admin/Plugins/GForum, do_func, CODE(0x83509f0), forum_view_collapsed).GForum (1705): GForum::do_func called at /home/virtual/domain.com/var/www/cgi-bin/forum/admin/GForum/Forum.pm line 25 with arguments (forum_view_collapsed).GForum (1705): GForum::Forum::view called at /home/virtual/domain.com/var/www/cgi-bin/forum/admin/GForum.pm line 292 with arguments (GForum::Forum, forum_view, HASH(0x84303f0)).GForum (1705): GForum::_plg_do_func_2 called at /home/virtual/domain.com/var/www/cgi-bin/forum/admin/GForum.pm line 240 with arguments (forum_view).GForum (1705): GForum::__ANON__ called at /home/virtual/domain.com/var/www/cgi-bin/forum/admin/GT/Plugins.pm line 105 with arguments (forum_view).GForum (1705): GT::Plugins::dispatch called at /home/virtual/domain.com/var/www/cgi-bin/forum/admin/GForum.pm line 240 with arguments (GT::Plugins, /home/virtual/domain.com/var/www/cgi-bin/forum/admin/Plugins/GForum, do_forum_view, CODE(0x8350bdc), forum_view).GForum (1705): GForum::_plg_do_func called at /home/virtual/domain.com/var/www/cgi-bin/forum/admin/GForum.pm line 231 with arguments (forum_view).GForum (1705): GForum::__ANON__ called at /home/virtual/domain.com/var/www/cgi-bin/forum/admin/GT/Plugins.pm line 105 with arguments (forum_view).GForum (1705): GT::Plugins::dispatch called at /home/virtual/domain.com/var/www/cgi-bin/forum/admin/GForum.pm line 231 with arguments (GT::Plugins, /home/virtual/domaincom/var/www/cgi-bin/forum/admin/Plugins/GForum, do_func, CODE(0x83509f0), forum_view).GForum (1705): GForum::do_func called at gforum.cgi line 101 with arguments (forum_view).GForum (1705): main::main called at /home/virtual/domain.com/var/www/cgi-bin/forum/admin/GT/Plugins.pm line 105 with no arguments.GForum (1705): GT::Plugins::dispatch called at gforum.cgi line 23 with arguments (GT::Plugins, /home/virtual/domain.com/var/www/cgi-bin/forum/admin/Plugins/GForum, main, CODE(0x83e9a4c)).System Information======================================Perl Version: v5.6.0Gossamer Forum Version: 1.1.3GForum.pm version: 1.109GT::SQL Version: 1.098GT::Template Version: 2.064DBI.pm Version: 1.18@INC = /home/virtual/domain.com/var/www/cgi-bin/forum/admin /usr/lib/perl5/5.6.0/i386-linux /usr/lib/perl5/5.6.0 /usr/lib/perl5/site_perl/5.6.0/i386-linux /usr/lib/perl5/site_perl/5.6.0 /usr/lib/perl5/site_perl .GT::SQL::error = No tree object exists for table 'Category'.
