我正在使用wordpress 4.1中的论文，我试图使用下面的功能按类别显示相关帖子，但当我转到帖子详细信息页面时，它会引发内部服务器错误。我在另一个网站上使用了相同的代码，该网站上的代码运行良好，两个网站上的每个代码单词都是相同的。我在这里被绊住了。我在php中增加了wordpress内存限制。ini文件内存限制，但也不起任何作用。所以请引导我使用下面的代码显示相关帖子。我想知道我在另外两个网站上使用的代码是什么，这两个网站都有论文主题，而且效果很好。

我在帖子详细信息页面上获取错误
Internal Server Error
The server encountered an internal error or misconfiguration and
was unable to complete your request.......................
a 500 Internal Server Error error was encountered while trying to use
an ErrorDocument to handle the request.

我已经解决了这个问题，我在测试服务器上测试了这个代码
我在帖子详细信息页面上看到错误错误是Fatal error: Call to undefined function short_title()
看到这一点后，我删除了函数代码short_title(); 从我的custom.php 并替换为the_title(); 显示标题。我已经检查了网站，一切都很好。
但我仍然不明白为什么这个函数short_title(); 无法在我的生产服务器上工作以及为什么它会引发Internal Server Error
除了这个错误Fatal error: Call to undefined function short_title()
