For staging purposes a mirror of a site name was created. In that mirror a fresh copy of WordPress was uploaded by ftp. With shell access, permissions were set to 755 for all files in the mirror’s directory. Attempts to complete the installation result in an immediate 500 error.
There are no instances of .htaccess in the path to …/wp-admin/setup-config.php
Creating a copy of .htaccess as appears at the WP codex at document root makes no difference
Permissions have been confirmed
I have noted that shell reports php as 5.5 whereas phpinfo() for the site shows 5.6
[*]There are no entries in error.log
So I’m stumped. What else to do?
