Create Issue option is missing in Agile Plan Mode after OD Release

The 'Create Issue' option in Agile Plan Mode is gone after the release on November 3rd 2014.

After the release, a few bugs were found in OnDemand. Some users are facing a bug similar to this one, but this one seems to be unrelated.

Workaround

Workaround 1: It's still possible to create issues from JIRA normally.

Workaround 2: Disable the "jira-inline-issue-create-plugin" plugin:

1. As a JIRA administrator, visit the add-on manager (Administration area >> Add-ons tab >> Manage add-ons).
2. Search for "jira-inline-issue-create-plugin".
3. Expand the plugin section.
4. Click "Disable".

Side-effect: This will disable the 'Create Issue' widget under each sprint section in Plan Mode. Users can still create issues using other means.
Note that this add-on will be automatically enabled again by Atlassian when the fix is ready. If you have any trouble with the workaround please contact Support.
