I had the plugin working in both the admin and in the template early on in my site development but I went to add a new image to a term today and it no longer allows me to set the image. I can click on the field name and the thickbox pops up. When I click on "Use This Image" the thickbox closes but the image url is not in the field.
Using WordPress 3.4.2 with custom taxonomies defined by Types, but it is not working within the post categories either. I have installed this on a second test site with the same version of WordPress and Types and it works. I have uninstalled and reinstalled the plugin as well as reinstalled WordPress. I have tried disabling all plugins except Types and this one.
I am experiencing the problem in Firefox, Safari and Chrome - but only on this one site. Have you seen this before? Any ideas?
