I am not sure but here is a suggestion. First lock your application to
2.3.2 by putting this at the beginning of environment.rb (watch out in
case there is already a line setting this up)
If you have the line in environment.rb then it should use 2.3.2
without having to freeze it in. Delete any rails directory in /
vendor in your application and try the app. If it is not using 2.3.2
there is something odd going on. Are you sure there is not a typo in
the version line in environment.rb?
