I'm using a 3.5.1 installation for one of my client with ACF version 4.1.6 - the latest one.
We've already filed the problem in StackExcahnge.com in THIS THREAD.
But for reference, I'm saying it again:
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.
Even the default WordPress editor is not working. Not even any AJAX in this page. :(
But I admire the plugin for its good support in all other sites I made for my client with a good respect to the sayings: Code is Poetry.
Thanks in advance to the author.
