如何调试、排错zen cart网店（出现空白页面）？

[zencarter]

错误提示应该在页面最后几行

我的网站迁移后在注册的时候出现空白。是提交注册信息后发生的， 虽然空白了，但是还是注册成功了，因为输入首页地址，显示的是刚注册的用户已经是登录状态，不过用这个用户再登录时提交登录信息后也是空白，打开了错误提示也没有错误提示的信息，在cache目录下也没有mydebug-xxx.log的前台日志文件，现在无从查找问题出在哪里了，大家帮帮忙吧！！！

通常情况是因为源代码首尾有空白行造成的。
用Dreamweaver，点编辑-查找和替换，然后选文件夹，只需要处理includes文件夹就能解决这一问题。
然后选源代码，而且选中使用正则表达式的复选框，最后选择替换全部。
用正则表达式删除首尾空白行
^[\s| ]*\n|\n[\s| ]*$
全部替换为空

可是这些文件都没有改过啊，不知道是怎么问题，高手请看看代码：


functions_general.php on line 776：以下是759--789的代码

代码: 全选

    if ( ($operator_count < $keyword_count) && ($balance == 0) ) {

      return true;

    } else {

      return false;

    }

  }





////

// Check date

  function zen_checkdate($date_to_check, $format_string, &$date_array) {

    $separator_idx = -1;



    $separators = array('-', ' ', '/', '.');

    $month_abbr = array('jan','feb','mar','apr','may','jun','jul','aug','sep','oct','nov','dec');

    $no_of_days = array(31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31);




init_templates.php on line 78：

代码: 全选

  $template_query = $db->Execute($sql);

  if ($template_query->RecordCount() > 0) {

    $template_dir = $template_query->fields['template_dir'];

  }



/**

* The actual template directory to use

*/

  define('DIR_WS_TEMPLATE', DIR_WS_TEMPLATES . $template_dir . '/');

/**

* The actual template images directory to use

*/

  define('DIR_WS_TEMPLATE_IMAGES', DIR_WS_TEMPLATE . 'images/');

/**

* The actual template icons directory to use

*/

  define('DIR_WS_TEMPLATE_ICONS', DIR_WS_TEMPLATE_IMAGES . 'icons/');


这个是functions_general.php on line 45：

代码: 全选

if (!defined('IS_ADMIN_FLAG')) {

  die('Illegal Access');

}

/**

* Stop from parsing any further PHP code

*/

  function zen_exit() {

   session_write_close();

   exit();

  }



/**

* Redirect to another page or site

* @param string The url to redirect to

*/

  function zen_redirect($url, $httpResponseCode = '') {

    global $request_type;

    // Are we loading an SSL page?

    if ( (ENABLE_SSL == true) && ($request_type == 'SSL') ) {

      // yes, but a NONSSL url was supplied

      if (substr($url, 0, strlen(HTTP_SERVER . DIR_WS_CATALOG)) == HTTP_SERVER . DIR_WS_CATALOG) {

        // So, change it to SSL, based on site's configuration for SSL

        $url = HTTPS_SERVER . DIR_WS_HTTPS_CATALOG . substr($url, strlen(HTTP_SERVER . DIR_WS_CATALOG));

      }

    }



  // clean up URL before executing it

    while (strstr($url, '&&')) $url = str_replace('&&', '&', $url);

    while (strstr($url, '&&')) $url = str_replace('&&', '&', $url);

    // header locates should not have the & in the address it breaks things

    while (strstr($url, '&')) $url = str_replace('&', '&', $url);

Jack:
public_html/includes/languages/french.php:1 是说这个文件第一行有错吗，但是我还原 本网站下载的原文件后，页面就出现Internal Server Error。
因为上传法语语言包后详细页面图片显示不了，在论坛查找，改了french.php中296行
把define('TEXT_CLICK_TO_ENLARGE', 'Agrandir l\'image'); 改成 define('TEXT_CLICK_TO_ENLARGE', 'Agrandir l\\\'image');

请问这是什么原因，请Jack和各位朋友帮忙看下。（还有上面两个点击所有按钮出现空白的问题）谢谢！
