上传特定尺寸的图像时出现HTTP错误

您好，我有一个经销商帐户，在共享主机上有一个wp 3.5 multisite。

突然间，我无法上传一些随机尺寸的照片（它可以上传小尺寸的照片，但大尺寸的照片有问题）。具体任何照片超过511（宽度）我得到了http错误，任何图像小于511（宽度）上传没有任何http错误

更新：这是我的功能。我的主题的phphttp://pastebin.com/ddEQqVJy

我们发现了问题，问题就出现了

第131行

add_image_size(\'theme-thumb\', 520, 497, true);

第267-275行

if (function_exists(\'add_theme_support\')) {
    add_theme_support(\'post-thumbnails\');
    set_post_thumbnail_size(150, 250); // default Post Thumbnail dimensions
}

if (function_exists(\'add_image_size\')) {
    add_image_size(\'post-thumb\', 310, 9999); //300 pixels wide (and unlimited height)
    add_image_size(\'widget-thumb\', 220, 180, true); //(cropped)
}

当我们把照片上传到媒体上时，它没有显示任何“HTTP错误”。

on函数。二十个十二的php

// This theme uses a custom image size for featured images, displayed on "standard" posts.
    add_theme_support( \'post-thumbnails\' );
    set_post_thumbnail_size( 624, 9999 ); // Unlimited height, soft crop

没有给出任何“HTTP错误”是很奇怪的，你知道为什么会发生这种情况吗？我怎样才能修复它？
