Hi,

Yesterday I installed markdown as a plugin ([http://www.railsdiary.com/](http://www.railsdiary.com/)  
diary/ajax\_markdown\_preview) and today for some reason I always get  
the error “undefined method `markdown’”, but it worked yesterday…

Do I have to reinstall the plugins every time I restart my server? Or  
is there something else I’m forgetting…

Thnx!
