I use the custom fields plugin to add metaboxes to my POSTS and PAGES. I also created custom post types, e.g. VIDEO.
Firebug gives me
win.send_to_custom_field("<a href=\"h...ze-thumbnail wp-image-312\" /></a>"); as reason. The image exists and can be inserted in POSTS or PAGES without a problem.
Any ideas? I am really confused...
Please help me. Wehn I deactivate the custom fields plugin all works.
