Hi Mark,
Thank you for the prompt response! I tried this again, using both Firefox and Safari (on a Mac), after clearing my cache, and the same problem persists. Unsure why, but 1) I enter content in the status update, and it fails to save/post; and additionally, I can't post a comment to your post on Stack Ideas (on CMS Connection). 2) None of my notifications work either. When I click on any of them, it fails to launch, and shows a "unable to load tooltip content" in a message alert. 3) When I click on "Add as connection" (friend), to try to add you as a friend, nothing launches/happens either. I also tested it using another test user - "johntest" - with the same results.
Want me to take a screencast (video) of it?
