Rails 5.0.1 placeholders are not working

Role.first
Role Load (3130.9ms) SELECT roles.* FROM roles ORDER BY roles.id ASC LIMIT ?
ActiveRecord::StatementInvalid: Mysql2::Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '?' at line 1: SELECT roles.* FROM roles ORDER BY roles.id ASC LIMIT ?

I also get this for all or most queries. It prevents the Rails app from starting.

Try setting prepared_statements: false in database.yml
