Greetings,
I am experimenting with a trial instance of Statuspage and the integration with Jira. I have my Jira project connected to Statuspage. I have an issue in Jira that shows the "Update status page" field on the right side. When I click that, it shows the name of the incident that is currently open in Statuspage, a "Link this incident" button that is greyed out, and a blue "Create new incident" button. 
The "Link this incident" button does nothing. The "Create new incident" button produces a "Sorry you can't open this. Refresh this page or try again in the next couple of minutes." message. Any explanation?
