Same problem with PS version 1.7.2.4

I've tried your fix but nothing changes.
My frontoffice is working well, but i can't login in my Backoffice (503 error)

someone have found a solution?

i've renamed the folder /modules/gamification and it actually works

It is the solution that prestashop has facilitated. I have done it and it has been solved. Can you show the files that you have modified?

Renaming the folder /modules/gamification also worked for me! Thanks Daniele Groff!
