dbo_source.php error

[neginf 0]

Getting warning 512, an sql error in dbo_source.php.There is no line number. There are warnings after that but hoping getting past the sql error will fix them.

It's a project written by someone else in CakePHP 1.3.2.

The MySql version is 5.6.

 

1.Is dbo.source.php a file that should be left alone ?

2.Is MySQL 5.6 too new for CakePHP 1.3.2 ?
