Error creating tables

I have the following error Can not create table 'base1.articles' (errno: 150) by passing the create table command to my database, which does not allow me to create the table posts within it

CREATE TABLE 'articulos' (
 'id' int(11) NOT NULL AUTO_INCREMENT PRIMARY KEY,
 'user_id' int(11) DEFAULT NULL,
 'title' varchar(255) NOT NULL,
 'slug' varchar(255) NOT NULL UNIQUE,
 'views' int(11) NOT NULL DEFAULT '0',
 'image' varchar(255) NOT NULL,
 'body' text NOT NULL,
 'published' tinyint(1) NOT NULL,
 'created_at' timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
 'updated_at' timestamp NOT NULL DEFAULT '0000-00-00 00:00:00',
  FOREIGN KEY ('user_id') REFERENCES 'users' ('id') ON DELETE NO ACTION ON UPDATE NO ACTION
) ENGINE=InnoDB DEFAULT CHARSET=latin1

that's my command for sql.
