How can I manually enable fisheye plugin

I disabled some plugins to upgrade Jira. The upgrade was not carried out as new version of Jira needs 64 bit hardware. Upon stopping and restartin开发者_C百科g the instance to resume with original application, I get this message:

The following plugins are required by JIRA, but have not been started:

FishEye Plugin (com.atlassian.jirafisheyeplugin)

catalina.out:

Does anyone have a clue as to how to re-enable fisheye plugin manually?

Any help greatly appreciated, thanks to all SO`ers.

This also happens when the update is succesfull and you've deactivates FishEye before. Sad.

There's an article in Atlassian's documentation at http://confluence.atlassian.com/display/JIRA/How+to+Enable+the+FishEye+Plugin+from+the+Plugin+Administration+Screen, but this doesn't work for me (note that the plugin name is written wrong there, too).

Any other hints?
