Permission denied in /public/index.php on line 28

Hi, first of all big thank you for response and also that you remind me for permission @ files 644 & dirs 755, that makes sense
I tried it, BUT my problems starts when i try to edit files from phpstorm

edited: and yeah i do not use apache pff, in post end i wrote my configurations, but u think maybe that it is signature?

so i followed https://serverfault.com/a/65416 guide, but i did not chown root:http,instead i did myuser:http, to be able edit files from IDE, anyway those permissions should be "normalized", before put those files on production, and also changed log file permission [app/Config/Logger.php] to 644 => 664, again to be able clear logs from IDE (i do it sometimes, don't blame me )
