How to fix the WordPress MU and Timthumb issue

WordPress MU is the multi-user version of WordPress. With WPMU you will be able to run a network of wordpress sites from your WPMU installation. Timthumb is a popular image cropping and resizing script being used in almost all my wordpress theme to handle featured thumbnails or slider images.  But there is a problem when you install the theme on a WPMU network, the featured images does not show up. This is due to the difference in which the file directory paths of WPMU and regular WordPress.  But there is a fix for it which will help the growing number of users running my themes on WPMU network.

So if you are using a WPMU setup and not able to get the thumbnails to work on my themes then the following,

  1. Open the functions.php file in your theme and locate the following function snippet – . Once located delete or comment it out.
  2. Then copy paste the code from this snippet to your functions.php file –

I have tested this fix to work on a WPMU setup.

    My host made me rename timthumb.php because of security problems with the script. I wonder how hard is it to remove it completely?
