I have come across this problem too many times to mention. I''ll assume you are running on UNIX. The consistent problems I have seen have to do with file and directory permissions or the location of ruby. What to try: 1. Check your dispatch.fcgi to make sure that you are pointing to the proper ruby executable. Try "which ruby" at the command line and see if the directory matches your dispatch.fcgi. 2. MOST LIKELY - Check your permissions. Usually it is the tmp folder, but it maybe something in your public folder as well. An easy test, but not something you want to use in production would be to just do a "chmod -R 777 *" in the project directory run your "apachectl graceful" to see if that is the problem then clean up from there. 3. Make sure you have a production.log and development.log files with appropriate permissions in your log directory which may help you isolate the problem although usually you don''t get far enough to get an actual log from rails when you get the dispatch errors.
