When I try to save any form in the CiviCRM admin area, I get this error:
Sorry but we are not able to provide this at the moment. We can't load the requested web page. This page requires cookies to be enabled in your browser settings. Please check this setting and enable cookies (if they are not enabled). Then try again. If this error persists, contact the site adminstrator for assistance. Site Administrators: This error may indicate that users are accessing this page using a domain or URL other than the configured Base URL. EXAMPLE: Base URL is http://example.org, but some users are accessing the page via http://www.example.org or a domain alias like http://myotherexample.org. Error type: Could not find a valid session key.
I have rebuilt my VM multiple times, and I'm fairly sure this has nothing to do with the cookie being set on the wrong domain.
What am I doing wrong? I hope this is me doing something stupid and not an actual bug, but I made a JIRA issue anyway: CRM-16508.
I have tracked the error message to this file, if that helps.
