We updated this blog several weeks ago, but suddenly the nothing was working. The whole frontend of this blog was blank, only admin was still working. Playing around with php installation, checking different templates and updating all plugins I tried everything without any success. Finally I deactivated all plugins and ….. the blog waws working again. So I hunted down the “black sheep” and it was:

cforms V 10.5

For now I removed this plugin, maybe I’ll later investigate a bit more what happend …

If you also have a blank screen but removing cforms does not help try these useful links:

Running Passenger on an apache machine to deploy a RoR application I suddenly encountered a default

403 Forbidden – You don’t have permission to access / on this server.

page generated from apache, although it was working before and I didn’t made a single change to my apache server. No real help from the log files:

Directory index forbidden by rule: XYZ

After some time of searching and banging my head against the wall I realized what I did wrong:
I’m using capistrano for “easy” deployment and I added a symlink linking always to the same server “environment.rb”. Of course I had a misstyping there and the symlink and thus the environment.rb was empty. So check your environment.rb file if you get such a 403 page, it may be empty….
