To put the fields on the primary key they must have a limitation. So, they can´t be TEXT fields. I have used smaller sizes for the fields because the index key can´t be longer than 1024 bytes. you can increase it if you want but i must not pass 1024 bytes (remember that the db is in utf8_general collation) This lines on env_setup.py file were modified to work with mysql: CREATE TABLE trac_unread ( username varchar(50), last_read_on integer, type varchar(50), id varchar(20), UNIQUE (type, id, username) );",enhancement,closed,high,TracUnreadPlugin,major,fixed,,,0.11
