为什么我的文件在我的本地环境中找到，但在我的cpanel服务器上找到了404

为什么这在我的本地环境下工作，而在我的生产服务器上运行cpanel:

$adminDir = get_bloginfo('template_directory');  
$adminDir = $adminDir."/lib/admin/";
$preview_file = $adminDir.'functions/live_preview.php';
wp_register_script( 'admin', $adminDir."js/admin.js", false, '1.0' ); //register script
$wp_paths = array( 'template_url' => $adminDir.'functions/live_preview.php');
wp_localize_script( 'admin', 'object_name', $wp_paths );
wp_enqueue_script("admin");

我不确定还需要提供什么信息，我在本地运行的是ubuntu和apache，我知道我的生产环境运行的是一些带有apache的linux。我有一些JS发送一个ajax请求的问题的页面:

    $.ajax({
        url: object_name.template_url,
        type: 'POST',
        data: { data: data },
        success: function(result) {
            kjd_reload_styles();
        }
    });

我在本地环境中没有得到任何错误，但是我的ajax响应在生产环境中导致404。为什么呢?

BUMP -所以有问题的文件是:

http://sandbox.kylejenningsdesign.com/wp-content/themes/bootstrappedWP/lib/admin/functions/live_preview.php

尝试点击，失败为404。但是如果你去它的父目录:

http://sandbox.kylejenningsdesign.com/wp-content/themes/bootstrappedWP/lib/admin/functions

您可以看到文件列表(顺便说一下，所有的文件都是404)。这是怎么回事?

这是我的。htaccess文件，它看起来像标准的wordpress。htaccess:

# BEGIN WordPress
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteRule ^index'.php$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /index.php [L]
</IfModule>
# END WordPress

新增错误日志:

我检查了我的cpanel错误日志，下面是我发现的。有两种类型的日志，一种显示最近的300条日志，还有一种更深入的日志。基本日志只显示这个(实际上，这个错误在今天我的ajax调用操作之后出现)
