I’ve seen this one posted, but not the solution. I have Radiant installed and the site section is working fine, but I get an application error when I try to go to the admin section. Running it with webrick locally on OS X machine. Anyone have any ideas? Thanks. ---

Could you please post the exact error output text? ---

That’s an internal server error. Then you might have WebBrick and apache trying to listen to the same port or have the radiantDir/public/dispatcher.rb misconfigured. ---

Look for the one that is relevant to the mode (production|development) that you are running in. – John L. [http://wiseheartdesign.com](http://wiseheartdesign.com) ---

It seems that you need to give Apache read/write access to the script folder. sudo chmod -R 755 ./script should help. ---

I usually get that problem with new Rails applications when the tmp/ directory doesn’t exist (especially if I checked them out of an SVN repo). Go to the root of your Radiant installation and run `rake tmp:create` . If it’s already there, you may have to chmod -R. Sean C. [seancribbs.com](http://seancribbs.com) ---

Thanks. It was the permissions on the tmp directory.

Yup. I usually use the recursive flag because I’m sure with all metaprogramming Rails does it probably uses tmp directories a lot. Not to mention session storage and management. So even though this time was easy to isolate to /tmp/sesh it’s just better to chmod the whole folder and its children. ---

Actually, it needs read/write access to tmp/sessions (actually, all of tmp) ---

The metaprogramming doesn’t really affect or deal with the tmp/ directory per se (There’s no compilation so you don’t have to rewrite class-files when you add to a class or change something). However, it is used to store session files, IPC sockets (for FCGI, etc), and the page/fragment cache – all of which are transient data that a running app needs. Sean
