Getting error:"Unable to communicate with server. Saving is not possible at the moment."in

Seeing this on a brand new install of Confluence 6.0.3 server, nothing customized yet.

Installed on Centos 7 virtual machine that is vanilla GUI install, with Firefox.  "Can't save changes" came up in the status bar of the editor almost immediately upon clicking edit.  Running the wiki and accessing it as   http://localhost:8090

Solution: Had to disable Confluence Collaborative Editor Plugin.

Still an issue.  Running hosted Confluence and local hipchat.   No % signs in document.  Confluence still does not allow saving when using Chrome.

Switched from Chrome to Safari, and it saves now.  The Confluence wiki page doesn't have any percent symbols, and we don't have the HipChat plugin.

This was a frustrating problem however it was resolved when I noticed Outlook was prompting for my network password. After entering my network password in Outlook I could publish the page.

I get this message when I try to edit a page I generated by a custom plugin. Only on the generated pages though...
