我正在使用CentOS 6；Apache 2.2.2；MySQL 5.6；PHP 5.5.31；WordPress 3.8.13。我没有此服务器的root访问权限，因为它是共享的。我有FTP和SSH（对功能有一些限制）。

在将一家机构的自定义Facebook像素添加到头文件后的最后3天内，我遇到了持续的内存过剩问题，导致网站显示Fatal Error: Out of Memory. 它可能与代码片段没有任何关系，只是碰巧发生在几乎同一时间。为了缓解这个问题，我增加了PHP。ini从100米到400米，以支持功能并增加观众。我仍然遇到内存不足的错误，但至少它没有显示在网站上（据我所知）。

错误日志显示：

每小时可能有一个错误。仍然需要修复它。接下来，我查看了PHP错误日志，它显示了：

PHP Strict Standards:  call_user_func_array() expects parameter 1 to be a valid callback, non-static method wf_gmp::init() should not be called statically in /mnt/12345/domains/domain.com/html/wp-includes/plugin.php on line 429

这些都是小错误。最后一步是我启用了WP Debug，它没有显示任何错误。下面的示例代码：

// Enable WP_DEBUG mode
define( \'WP_DEBUG\', true );
// Enable Debug logging to the /wp-content/debug.log file
define( \'WP_DEBUG_LOG\', true );
// Disable display of errors and warnings
define( \'WP_DEBUG_DISPLAY\', true );
@ini_set( \'display_errors\', 0 );
// Use dev versions of core JS and CSS files (only needed if you are modifying these core files)
define(\'SCRIPT_DEBUG\', true);
if (WP_DEBUG) ini_set(\'display_errors\',1);

所以，要么1。Apache或PHP错误（不一定）是WordPress错误。或者我的调试模式似乎被打破了。但我以前在这个网站上用过。
