  CONFIG_TEXT: AH00526: Syntax error on line 31 of /etc/httpd/conf.d/php.conf:
  Invalid command 'php_value', perhaps misspelled or defined by a module not included in the server configuration

• suPHP module is installed.

Cause

Resolution

Warning: suPHP is not supported by Plesk

Disable suPHP module in Tools & Settings > Apache Web Server Settings

Or

1. Log in to Plesk server using SSH.

2. Find strings with php_value in Apache config files and comment them:

   # grep -ir 'php_value' /etc/httpd/ | cat
   /etc/httpd/conf.d/php.conf:# php_value session.save_handler "files"
   /etc/httpd/conf.d/php.conf:# php_value session.save_path "/var/lib/php/session"
