Site gone after update…

Today I updates my site with Minamaze theme. I always change the ‘Read More’ into Dutch ‘Lees verder’ in 00.theme-setup and 02.homepage, but after doing that, my site is invisible (the code is there, it’s just not showing anything).

Of course I didn’t do a backup first since I’ve done the several times before (my bad)

Is there anyway to fix this?
