I'm seeing the same thing with JForum 2.1.4 / MySQL 4.1.14 /
Tomcat 5.0.27 too.
Go to: Admin Console - Groups / "General" / Permissions - then save.
This error is returned:
An error has ocurred. For detailed stack trace, please see the page's source code.
Unknown table 'jforum_role_values' in MULTI DELETE
I was trying to disable anonymous posting for my forums when I found it. And, the table exists with data in it.
From a web search:
"This is expected behavior for MySQL post version 4.1. Check out:
http://dev.mysql.com/doc/mysql/en/DELETE.html
particularly the 'Note:' section just before the user comments. If you use table aliases you must use those aliases to refer to the tables you want to delete, not the table names themselves."
