I am using the plugin: Advanced Custom Fields. For several more images, I used it to add images using the image input field.
Now, when I edit a post, I can't edit/add new image into the image field using the plugin. Using Firebug, it shows a js
error:
Uncaught ReferenceError: tb_show is not defined
But the same fields work, when I add a new image using those fields.
wp_enqueue_script( 'thickbox' )
to yourfunctions.php
?
