Impossible to delete a flash

I made a mistake before migrating a plugin, and have written

flash[:notice] = :label_presta_added


instead of

flash[:notice] = l(:label_presta_added)


I corrected my mistake but it seems that my Redmine Plugin has trashed my Redmine. Even though I delete my plugin a migrate once again, I still get this error:

Started GET "/" for 127.0.0.1 at 2016-06-01 22:21:37 +0200

Can somebody give me a hand here?
Thanks in advance!

Answer

This is stored in your session, so usually changing the session secret key will invalidate all sessions and discard any old session data.

You can also try and rescue to clear it out as a one-time deal.
