How to Enable the FishEye Plugin from the Plugin Administration Screen

When navigation to the Fisheye Plugin page under, Administration > Plugins > FishEye Plugin, JIRA shows that the plugin is disabled and the enable link to activate the plugin is missing. This occurs if the FishEye plugin was disabled in a previous version of JIRA. After an upgrade of JIRA, the enable link in Plugin Administration is missing. First paste the following URL into your web browser as the JIRA Administrator:

http://<JIRA--BASE_URL>/secure/admin/jira/ViewPlugins.jspa?mode=enable&pluginKey=com.atlassian.jira.ext.fisheye

If that fails to resolve the issue, then run the following SQL Query:

update propertystring set propertystring.propertyvalue = 'true' where propertystring.ID IN (select ID from propertyentry where propertyentry.PROPERTY_KEY = 'jira.plugin.state-.com.atlassian.jira.ext.fisheye');
