I have installed TikiWiki 1.9.5 on a Gentoo Linux install, Apache is running Virtual Hosts to allow for a blog server and a wiki server at different hostnames.
I have found TikiWiki relatively easy to configure, but have run into an issue. I created a new Group called "Wiki_Editors", and I want to allow additional access to rename, delete and rollback wiki entries to these users.
I created the group, and clicked on the key icon for permissions, but when I select the permissions and hit update I end up receiving the error message
and I have been logged out. The URL of the page is
I have downgraded to 1.9.4 and have the same problem, so I went back to 1.9.5.
I looked at the tiki-assignpermissions.php versus tiki-assignuser.php (which works for me) and they seem to have the same tests at the top.
I also output the $user and $tiki_p_admin variables as part of the error message and $user is empty and $tiki_p_admin = 'n'.
Any help appreciated.
