Redmine

Hi,

I've just installed the wiki plug-in to my Redmine. After I change my settings to use 'Wiki Extenstion' in my redmine, I get an error message as below.

"undefined method `wiki_extensions_get_current_page'"

I have no idea what went wrong with that. Currently I'm using :

- Redmine 0.8.4 revision 2778
- Windows xp sp3
- MySQL 5.0.33

Please check if you guys can give me any of advise or solution for the problem above.

Thank you.
