Orca posts area never loads - spinning ajax wheel

The posts area on the orca forum never loads. There are no posts but something should happen other than an eternal spinning wheel - right?   This is a virgin install of 7.0.2. No customizations and No custom  template - Im using UNI.

Any advice greatly appreciated.

It's time for another round of questions!

• Is allow_url_fopen enabled for your PHP configuration?
• Did you recently change domains or directories on your server?
