Can't get comments to work....
Installation and Configuration
It doesn't always have to do with the skin, but its best if we try to replicate using as close to the same setup your using just in case it does have to do with the skin.
In this instance, I'm not able to replicate your issue, I can comment on galleries and gallery images without issues, so it is probably how you have your settings in the ACP.
Can you send us your site URL and admin login so we can check it out?
Send it to support[at]jamroom[dot]net
Thanks!
