Installed the plugin but on adding a link to it by going to Admin > Pages after I setting up database tables, its showing this error and link isn't getting added ---->
Question2Answer query failed:
INSERT INTO qa_pages (title, nav, flags, permit, tags, heading, content, position) VALUES ('Chat Room', '', 1, 40, 'chat', NULL, NULL, 7)
Error 1062: Duplicate entry 'chat' for key 'tags'
What is this problem ? How can I rectify it ?
