我已经在本地机器上配置了 testlink。从“结果”菜单中选择“基于需求的报告”时,一切正常,显示以下内容DB Access Error

 DB Access Error - debug_print_backtrace() OUTPUT START 

 ============================================================================== 

#0  database->exec_query(SELECT id FROM xp_executions WHERE  tcversion_id=(SELECT id FROM xp_nodes_hierarchy  WHERE parent_id='0') ORDER BY id DESC LIMIT 0,1, -1) called at [D:\wamp\www\testlink\lib\functions\database.class.php:535]
#1  database->fetchRowsIntoMap(SELECT id FROM xp_executions WHERE  tcversion_id=(SELECT id FROM xp_nodes_hierarchy  WHERE parent_id='0') ORDER BY id DESC LIMIT 0,1, id, 1) called at [D:\wamp\www\testlink\lib\results\resultsReqs.php:103]

 ============================================================================== 

我在谷歌上搜索了DB Access Error - debug_print_backtrace() OUTPUT START错误,但没有找到任何解决方案。

我的主要问题是什么是debug_print_backtrace()错误,为什么会出现?其次是如何删除它?
