Could you please add thickbox js and css file in your installation so people can use it easily?

I’m not sure what the issue is, but for some reason the WP Thickbox Integration Plugin (https://www.ads-software.com/extend/plugins/wp-thickbox-integration/) does not play nicely with Advanced Custom Fields (https://www.ads-software.com/extend/plugins/advanced-custom-fields/).

If I setup an Image field in ACF, while the WP Thickbox Integration plugin is enabled, whenever I click “Select Image” in the admin panel, it doesn’t actually select the image. Once I disable the thickbox plugin, everything works properly with ACF again.

I can build the thickbox functionality directly into my theme, so I’ve disabled the thickbox plugin in favor of ACF. Not sure which plugin is actually causing the problem though.
