Update: This is my functions.php of my theme http://pastebin.com/ddEQqVJy

We find the problem , the problem is on

line 131

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

lines 267-275

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)
}

When we took them off it didn't show any "HTTP error" when we uploaded a photo on media.

on function.php of Twenty Twelve use

// 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

without giving any "HTTP error" is strange, do you know why is this happening? And how can I fix it?

Answer 1

Using LiteSpeed with php 5.3 + Wordpress 3.5 will require to increase External App >> lsphp5 to these values :

Memory Soft Limit = 777M

Memory Hard Limit = 800M

Amazing values for memory setting, but it works for me.
