Website or some parts are inaccessible: pcfg_openfile: unable to check htaccess file

Symptoms

• Website or some parts are inaccessible (for example, directory with css files);

• Errors in /var/www/vhosts/system/example.com/logs/error_log file:

  CONFIG_TEXT: [crit] [client 203.0.113.2] (13)Permission denied: /var/www/vhosts/example.com/httpdocs/css/.htaccess pcfg_openfile: unable to check htaccess file, ensure it is readable, referer: http://www.example.com/index.html

  Note: the path in bold may differ, e.g it may point to the WordPress theme like /var/www/vhosts/example.com/httpdocs/wp-content/themes/theme_name/.

Cause

Incorrect permissions inside the docroot.

Resolution

1. Connect to the server via SSH.

2. Set permissions on the directory mentioned in the error:

   # chmod 0755 /var/www/vhosts/example.com/httpdocs/css/

3. Set the correct ownership

   # chown john_doe:psacln /var/www/vhosts/example.com/httpdocs/css/

   Note: put subscription system user instead of john_doe. The system user can be found in Plesk > Domains > example.com:
