I’m not sure if this question will be supported as it involves getting a traditional WordPress Theme (Business Bite) to work with WPMU. When I installed the theme and tried to activate the theme I got the following error:
Fatal error: Call to undefined function: add_theme_support() in /home/biovedaw/public_html/wp-content/themes/business_bite_dev/functions.php on line 3
So I removed the following lines of code from the functions.php file of the theme (per the theme developer’s suggestion) and I’m able to activate the theme.
add_theme_support( 'post-thumbnails' );
set_post_thumbnail_size( 375, 250, true ); // Normal post thumbnails
Everything works at this point except that the images in the feature slider (post thumbnails) are not loading (which I’m assuming is because I removed the above lines of code which were causing a fatal error and therefore I’m unable to assign an image as a “thumbnail” for the purpose of being used in the feature slider.
Any ideas as to how I can get the theme to load and activate in it’s entirety without causing the fatal error? I’m thinking it may be related to timthumb and the image path in wpmu being different than in a traditional wordpress install. Any help, advice, direction would be greatly appreciated!
I’ve attached the functions.php file that was causing the error and the slider.php file from the theme.
Thank you,
