site5 uninitialized constant NameError

Hi everyone, I just trying to migrate/upload my application to site5 server and I had this error and have no idea where should be or why because in my computer doesn't give this error. Maybe because they use apache or something like that.

These are the possible causes: There may be a syntax error in the application's code. Please check for such errors and fix them. A required library may not installed. Please install all libraries that this application requires. The application may not be properly configured. Please check whether all configuration files are written correctly, fix any incorrect configurations, and restart this application. A service that the application relies on (such as the database server or the Ferret search engine server) may not have been started. Please start that service. Further information about the error may have been written to the application's log file. Please check it in order to analyse the problem.
