RPC: request rejected (bad origin) in Confluence Development instance

[Adrian Smith]

I am working on a Confluence plugin, and all of the sudden today found that I am unable to create spaces in the Confluence Development instance, the create page just loads forever:

I can browse the rest of the instance fine, including things like configuring the plugin I am working on. I was able to create pages with the same plugin yesterday.

I have created an empty plugin with `atlas-create-confluence-plugin`, and the issue still occurs there after using `atlas-run`. Looking at the console log in Chrome the issue appears to be an error:
`RPC: request rejected (bad origin): http://5cg61629pv:1990`

This seems to indicate some sort of Cross Origin issue, but I can't trace the problem any further than that.

I have tried:

* Rebooting Chrome
* Rebooting machine
* Rebooting and rebuilding development instance
* Turning off all malware/firewall software
* Tried in Chrome, IE, Edge

I have also tried with Confluence versions 6.2.0 and 6.2.2.

I can't think of anything else to try, so any help is welcome.

Based on your initial theory that the issue is XSRF related, please check the logs for the errors in After upgrading Confluence, you are unable to create new pages or spaces

I have seen the editor hang when the base URL is not the same as the URL being used in the browser. Please check your base URL at Confluence Admin>General Configutration.

I did faced this issue earlier in local instance. You need to turn off the Collaborative Editing in General Configuration screen.
