I have the same problem with the email translations, click save, redirects to website with admin address in the address bar and says... Page cannot be found.
It doesn't save at all.
I upgraded from 1.7.1 to 1.7.2.0 thinking that might fix the problem but it didn't, no errors show in the error log, cache cleared, tried doing it manually in the files but it doesn't change.
It would be good if it worked straight from the back office.
Can anyone help please
