as well into gpconfig.php though I don't know if that works anymore.
Anyway, I could access and change most config settings, but I could not edit pages. When I click edit with debug turned on I get this:
thrownError = SyntaxError: missing ) in parenthetical
with debug off:
There was an error processing the last request. Please reload this page to continue.
If you look in your nginx log and see something like:
open() "//var/lib/nginx/tmp/fastcgi/1/01/0000000011" failed (13: Permission denied) while reading upstream
your problem is coming from permissions being wrong on /var/lib/nginx which need to be set to the user and group nginx runs under.
I don't know if anyone else will have this problem, but if editing is not working, dig deeper into nginx logs and see if this isn't at the root.
It looks you solved the problem the wrong way around. Your webdirectory needs to permit the nginx user to modify the file.
