hi -
Anytime I change my user layout for example (1 user only now, as I am making test before going to prod), the display is basic text html (white page, options as text on the left with link).
Randomly I ran chmod -R 775 cache custom modules themes data upload , and then the display is correct. If I change the layout again, I need to throw this command again.
I have done this but as I said, anytime something happen (for example I just uploaded a logo), I need to re-apply all the permissions. I did not check what are the permissions of the new files though. It might be a system setting rather than this?
