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,
- Open the functions.php file in your theme and locate the following function snippet – http://snippi.com/s/zck93rs . Once located delete or comment it out.
- Then copy paste the code from this snippet to your functions.php file – http://snippi.com/s/xh71vze
I have tested this fix to work on a WPMU setup.
