unable to start new topic

2nd Feb.-did a search of 'Digital Republic' for "Stefani", and wanted to start a new topic. I was greeted with a screen containing a large blue triangle warning stating that the object was missing. Mind you, I use the latest version of Safari for the most recent version of Mac OS X. But this doesn't seem to cause trouble elsewhere. I'm sure it'll correct itself, but wondered if anyone else had encountered this problem. Thanks very much for anything you can do. Best....Villager
