I getting that for kfm_directories, too:
SQL query:
--
-- Dumping data for table `kfm_directories`
--
INSERT INTO `kfm_directories` ( `id` , `name` , `parent` , `maxwidth` , `maxheight` )
VALUES ( 1, 'root', 0, 0, 0 ) ;
MySQL said: Documentation
#1062 - Duplicate entry '1' for key 1
There has to be something I'm not doing correctly.
