apache日志提示错误:

PHP Fatal error:  Call to a member function setNumPublishedArticles() on a non-object in D:\\Apache\\htdocs\\lifetype\\class\\dao\\articles.class.php on line 667, referer: http://localhost/lifetype/wizard.php

PHP Warning:  Invalid argument supplied for foreach() in D:\\Apache\\htdocs\\lifetype\\class\\dao\\articles.class.php on line 1244, referer: http://localhost/lifetype/summary.php

我现在不能新建文章分类,和发表文章.lt的sql_error.log报告：
INSERT INTO `lt_articles_categories` (name, url, blog_id, parent_id, description, in_main_page, last_modification, properties, num_articles, num_published_articles, mangled_name) VALUES ('aa', '', '1', '', 'aa', '0', '20060610115148', '', '0', '0', 'aa')generated the following error message =
Out of range value adjusted for column 'parent_id' at row 1

请问以上错误如何解决,谢谢!
