I tried to translate interface with version 9.0.1. I created the folder application/languages/site and made it writable as usual. Nothing happens, file not found.
There seems to be missing the button “Reload strings” that used to work with version 8. Is this supposed to work without those buttons, or am I missing something else?
Edit. Now I noticed buttons show only after the application/languages/site folder is found. With version 8 it works, with 9.0.1 folder is not found. I tested with both versions, and they have same folder permissions.
