Hi Jong-dae,

can you please open a bug report in any case so we have the chance to fix it?

Back to your question, do you simply want to remove it temporarily to check whether the bug is caused by the plugin or do you want to get rid of it permanently?

If you want to remove it completely you have to do two things (in the mentioned order)

1) remove traces of the plugins data from the db. Backup your database before you do so!
In the folder you installed OpenProject execute:

bundle exec rake db:migrate:down VERSION=20130822113942
bundle exec rake db:migrate:down VERSION=20130731151542
bundle exec rake db:migrate:down VERSION=20130822113942

2) remove the meeting entry from Gemfile.plugins.
It will probably look like this:

gem "openproject-meeting",         :git => "git@github.com:finnlabs/openproject-meeting.git",       :branch => "dev"

In case you only want to try out whether the plugin is problematic, you only need to do the second step (you can just comment it out then by adding a “#”-sign to the beginning).

Best

Jens
