Problem installing on FastCgi Plesk Domain

    Hi,

    I am having a real headache installing this plugin on one of the domains on a plesk server 12.0.18 (php v5.3.3-40.el6_6) which runs as fastCGI.

    I have tried php.ini .user.ini and php5.ini placed manually and automatically and all of them result in an error about the firewall not being loaded.

    I have tried putting it into the field for extra php directives within plesk ui etc, which gives me a blank page with no error. The error logs for the site show two errors:

    —-
    mod_fcgid: stderr: PHP Notice: session_start(): ps_files_cleanup_dir: opendir(/var/lib/php/session) failed: Permission denied (13) in /var/www/vhosts/sitename.info/httpdocs/wp-content/plugins/ninjafirewall/lib/firewall.php on line 253

    (AND AFTER AN UNINSTALL)
    mod_fcgid: stderr: PHP Warning: Invalid argument supplied for foreach() in /var/www/vhosts/sitename.info/httpdocs/wp-content/plugins/ninjafirewall/uninstall.php on line 86, referer: http://www.sitename.info/wp-admin/plugins.php?action=delete-selected&checked%5B0%5D=ninjafirewall%2Fninjafirewall.php&plugin_status=all&paged=1&s&_wpnonce=536ab05b77
    —-

    I have run the ninjacheck file which shows the firewall isn’t being loaded for it either.

    Weirdly I seemed to install it correctly quite quickly previously, though the log didn’t populate after a while.

    After the upgrade today it won’t work at all. I have tried everything on the troubleshooting page to the best of my ability without success.

    I also run wordfence – I wondered if for some reason the updated version conflicted with it, though I don’t think it would. The problem occurs whether or not the wordfence plugin is active.

    Could you offer any advice as to what to try next please?

    Thanks,

    Jim

    Hi,

    It seems to me that you cannot use PHP INI in the document root folder in Plesk 12 but that you need to use “/var/www/vhosts/system/YOUR_DOMAIN.TLD/etc/php.ini” instead.

    1. run the installer.
    2. select Apache + CGI.
    3. scroll down and select “I want to make the changes myself”.
    4. copy the instructions and paste them into “/var/www/vhosts/system/YOUR_DOMAIN.TLD/etc/php.ini”
    5. finish the installation.

    Hi,

    Thanks for getting back to me. I did so (as I tried before). It errors:

    “NinjaFirewall fatal error : Unable to communicate with the firewall. Please check your PHP INI settings. Review your installation, your site is not protected.”

    Any other ideas?

    Kind regards,

    Jim

    Hi,

    I think I found the problem: PHP 5.3 does not support the PHP header_register_callback() function. That is why you get the blank screen (PHP error).
    I made a small change to the firewall script and forgot about that.
    PHP 5.3 reached end of life last year but still many sites are using it.

    I will patch the firewall.php script today.
    In the meantime you can try to comment out (or delete) lines 82 to 86:

    // Response headers hook :
if (! empty($nfw_['nfw_options']['response_headers']) ) {
	define('NFW_RESHEADERS', $nfw_['nfw_options']['response_headers']);
	@header_register_callback('nfw_response_headers');
}

    Then try to install it again and use Plesk UI to add the directives.

    Thanks nintechnet.

    That got it working. I am convinced that it is responsible for thwarting the admin-ajax based attacks I have been suffering lately, so thanks very much for fixing it for me!

    Kind regards,

    Jim
