Symptoms
When trying to access an attachment in JIRA after migrating from JIRA Cloud (OnDemand) to JIRA Server (Behind the Firewall), JIRA shows a 500 error page with a "java.lang.IllegalStateException: BlobStore Client Plugin not loaded" message.
The following appears in the atlassian-jira.log:
2014-09-04 19:10:20,824 http-bio-8080-exec-1 ERROR jtabeling 1150x15324x1 1xp3ogl 192.168.10.XX,127.0.0.1 /secure/attachment/10405/MyScreenshot.png [jira.web.servlet.ViewAttachmentServlet] Error serving file for path /10405/MyScreenshot.png: BlobStore Client Plugin not loaded

at com.atlassian.jira.issue.attachment.BlobStoreAttachmentStore.get(BlobStoreAttachmentStore.java:57)
Cause
JIRA Cloud has the Atlassian BlobStore Client Plugin to manage its attachments. This plugin is not currently available for JIRA Server, and during the migration, the dark feature flag is not disabled - this is currently being tracked on JRA-39836 - Getting issue details... STATUS .
Resolution
- Access the Dark Features page in the JIRA Server through http://<jira-address>/secure/admin/SiteDarkFeatures!default.jspa
- Disable the com.atlassian.jira.FS_ATTACHMENTS_PRIMARY dark feature.
