Syntax Error Causing Passenger on Apache to Break Redmine
I encountered an error while working on project.altservice.com in which the page would not load, producing nothing but a "syntax" error from Passenger. Even though I did not find out what caused this problem, I removed the RackMultipart files in the Redmine directory:
rm -rf RackMultipart*
Once this was finied, I ran bundler to reinstall Redmine for good measure:
bundle install --without development test
This fixed the problem.
