Depending on autocommit is a bug [when does commit happen then?  consistency is a real problem].  Code should always explicitly ate least COMMIT or ROLLBACK if not explicitly BEGIN.  Not to mention how much easier it makes it to read the code and understand the units of work.

>Well, have you changed anything in your database configuration?

a big downside of autocommit - backend changes can break you app
