Blogsmu no buttom to upload avatar on group

Dunno if this is a borked install or a real bug.

Trying to change avatar for this group :http://australianracinggreyhound.com/network/groups/greyhound-racing/

Got to Admin >> Group Avatar

I have a "Choose" button to choose the file but no save or upload button.

Also noticed in the forum - Ihave a "new topic" button and can write a post but there is no "save" or "post" button
