Problem

When a user navigates to certain JIRA projects, the error below is displayed when trying to view attachments:

A similar error to the following appears in the JIRA logs after replicating the error:

[java.lang.Exception: com.atlassian.confluence.rpc.RemoteException: You're not allowed to view that page, or it does not exist.]

2015-06-02 16:31:21,965 TP-Processor14 WARN sysadmin 991x2485x1 1tdtyha 131.103.28.240,104.192.140.241 /secure/AjaxIssueAction!default.jspa [jira.issue.attachment.FileSystemAttachmentDirectoryAccessor] Unable to make thumbnail directory 

Cause

Even though the attachments for that issue exist in the file system, the application does not have access to retrieve the information or create a thumbnail preview to de displayed in the issue.

Resolution

The owner/group of the attachment needs to be updated so that the application can retrieve the attachment.

• Support can do this recursively for the attachments in JIRA Cloud by running the following:

  chown -R js-jira:js-apps /data/jirastudio/jira/home/data/attachments/
