When does that show up..? What are you trying to do?

Okay a little bit more details:
View an image in gallery and klick on "Comments". Nothing's happend. If you click twice the quick reply field appears. Now type your comment and click "Post".
Output:
Comment was left empty
Here on wedge the Comment field will open as soon as clicked.

Honestly, it's working on my local install as well... And I never changed a thing regarding media perms... :-/

Hmm.. will install it on another server and give it a try. Also refreshing of thumbnails didn't work for me. Perhaps it's a server thing.

My goal is to make it work everywhere...
If you still have problems in the future, and you're willing to share your FTP details... (known song.)
