REDMINE Owner/Permissions on Servage Hosting

Permission denied ...
this error message appears often on Servage Hosting Spaces. You can solve the problem in setting the right owner/permission. Try to avoid 777 - instead you should use "webserver" as owner.

The following folders need to be set to "webserver"

1. files (otherwise you can't upload files)
2. log
3. tmp

If you receive this:

1. Errno::EACCES in ProjectsController#add_document
   then your files folder is not set to "webserver"
