- Apache fails to start during Obsidian upgrade/installation. The error is logged in
/var/log/plesk/install/autoinstaller3.log:
Invalid command 'php_value', perhaps misspelled or defined by a module not included in the server configuration- httpd -t shows a similar error:
#httpd -t

- OS PHP is used with version 5.4:
#php -v

php_value session.save_handler "files"
php_value session.save_path "/var/lib/php/session"- Tools & Settings > Apache Web Server Settings > php5 is disabled.
