TimThumb on MultiSite: "Could not create the index.html file" WordPress

Francisco Javier Carazo Gil answers:

Hi,

I have experience in this problem using WordPress network and MU. To solve it:
1. Download timthumb from his website: http://code.google.com/p/timthumb/
2. Look for this:
// -------------------------------------------------------------
// -------------- STOP EDITING CONFIGURATION HERE --------------
// -------------------------------------------------------------

3. Below this add:
// FIX MU 1
require( $_SERVER['DOCUMENT_ROOT'] . '/wp-load.php' );

4. So it will be now:
// -------------------------------------------------------------
// -------------- STOP EDITING CONFIGURATION HERE --------------
// -------------------------------------------------------------

// FIX Multisitio 1 de 2
require( $_SERVER['DOCUMENT_ROOT'] . '/wp-load.php' );

timthumb::start();

5. Now you have to find this:
protected function calcDocRoot(){
$docRoot = @$_SERVER['DOCUMENT_ROOT'];

6. And below add:
// FIX MU 2
if (is_multisite())
{
global $blog_id;
if (isset($blog_id) && $blog_id > 0)
{
$docRoot .= '/wp-content/blogs.dir/' . $blog_id . '/';
}
}

7. So it will be now:
protected function calcDocRoot(){
$docRoot = @$_SERVER['DOCUMENT_ROOT'];

/// Fix Multisitio 2 de 2
if (is_multisite())
{
global $blog_id;
if (isset($blog_id) && $blog_id > 0)
{
$docRoot .= '/wp-content/blogs.dir/' . $blog_id . '/';
}
}

8. Save the file modified and then upload it to your theme (wp-content/themes/your-current-theme)

If have further questions tell me.
