  PLESK_ERROR: Error: phpinimng failed: configuration test ‘/usr/sbin/php-fpm –test’ failed with code 78, and message: ERROR: [/etc/php-fpm.d/www.conf:1] value is NULL for a ZEND_INI_PARSER_ENTRY ERROR: Unable to include /etc/php-fpm.d/www.conf from /etc/php-fpm.conf at line 1 ERROR: failed to load configuration file ‘/etc/php-fpm.conf’ ERROR: FPM initialization failed

• In some cases, the following error message appears on the Home page in Plesk:

Cause

This is a Plesk bug with ID PPPM-9483, which was fixed in Plesk Obsidian as PPP-38933.

Such behavior occurs after upgrading system PHP to 7.x version. PHP 7.x treats prefixes “#” and “;” differently.

Resolution

Upgrade to Plesk Obsidian.
