Hi,
Try to follow these steps and see if it helps.
Regarding the INI file, you will probably need to use .user.ini.
Hi,
Still getting White Screen.
I set
output_buffering = 4096
session.save_handler files files
session.save_path /tmp /tmp
Wp Debug says:
Warning: session_start(): Cannot send session cache limiter – headers already sent (output started at /home/mywebsite/public_html/wp-includes/functions.php:2908) in /home/mywebsite/public_html/wp-content/plugins/ninjafirewall/ninjafirewall.php on line 45
Any suggestion?
Line 2908 of /wp-includes/functions.php shows that WordPress will display an error message because a plugin is using a deprecated function. Because of that, you get an error when NinjaFirewall is calling the PHP session_start() function.
Can you try to disable each plugin one by one, until you can find which one is the problem ?
Hi,
I installed a brand new install of WP and Ninja Firewall. I still white screen.
Now my setup is this:
Varnish (Cache)–Nginx (reverse proxy) –Apache
Which might be why its white screening.
Server also has ModSecurity with Commodo WAF Rules.
Any advice. Thanks
DUH. I fixed it. Firewall was blocking me and doing its job.
You might have to Whitelist your Internet IP.
I personally used the user.ini
Here is the Tutorial:
http://nintechnet.com/nfwp/1.1.3/
Brief Run Down:
In the plugin directory look for the file:
.htninja_example
“This file must be named .htninja and must be located in the folder above your website document root : if your document root is /home/user/public_html/, the location of the file will be /home/user/.htninja “
Look for the lines in that .htninja file:
// Whitelist single IP 1.2.3.4:
if ( $_SERVER[“REMOTE_ADDR”] == ‘YOUR IP ADDRESS’ ) {
return ‘ALLOW’; // whitelist
Replace YOUR IP ADDRESS with your Internet IP address.
Multiple IP, find the corresponding line.
Save and then enable the plugin.
Then fix permission to read only or 444 on the .htninja file.
CLOSE TICKET AS SOLVED.
Your problem is not solved. By adding your IP, the firewall will stop running immediately. That is why you don’t get any more errors.
In most case, the white screen means there is a PHP error. Now you need to force PHP to display and/or log that error so we’ll know what is going on. See php.ini Error Settings
I finally got PHP ERRORS TO DISPLAY:
In my user.ini
I placed:
error_reporting = E_ALL | E_STRICT
display_errors = 1 (On didn’t work)
session.save_path = tmp
Created a tmp folder in root with permissions
Errors Received:
Warning: session_start(): open(tmp/sess_4d1d46f1875d88532a68adbca303148d, O_RDWR) failed: No such file or directory (2) in /home/directory/public_html/wp-content/plugins/ninjafirewall/ninjafirewall.php on line 45

I just see line 45 Error:
if (! session_id() ) { session_start(); }
Tried to look for Php Coding Errors and found this discussion.
http://stackoverflow.com/questions/6865957/php-logic-for-session-id-and-session-start
Any advice?
session.save_path = tmp
You need to add the full path to that directory otherwise you will keep getting that “No such file or directory” error.
Just did that. No more PHP errors.
I could see the session.save_path working and files being created/
WP-Debug has no errors.
Still white screening.
I then checked your FAQ.

Blank page after installing NinjaFirewall :
In some cases, right after installing it, you may get a blank page and/or the following error message :
Warning: session_start() [function.session-start]: Cannot send session cache limiter – headers already sent (output started at …/…/wp-content/plugins/ninjafirewall/lib/firewall.php…
The problem may come from your PHP session save handler (session.save_handler) configuration which is not set up to use files.
HERE IS MY SESSIONS from phpinfo:
session.auto_start Off Off

Can you try to edit ninjafirewall.php and to comment out lines 43, 44 and 46.
Add ‘//’ at the beginning of the 3 lines so that it looks like this:
// add_action('init', 'nfw_sessionstart', 1);
// function nfw_sessionstart() {
if (! session_id() ) { session_start(); }
//}
Just keep line 45.
OK.
So I installed WP to brand new domain and the Only plugin is Ninja Firewall.
I commented out lines 43, 44 and 46.
In NinjaCheck.php I get the following 2 messages referencing Line 45:
Warning: session_start(): Cannot send session cookie – headers already sent by (output started at /home/directory/public_html/ninjacheck.php:25) in /home/directory/public_html/wp-content/plugins/ninjafirewall/ninjafirewall.php on line 45

I also sent a request for install help thru your site. I may just have a funky system that needs your help.
Note that if you sent us a ticket for the installation, you will not get an answer before April 18th because of holidays here in Thailand.
I understand about the Holidays. If your not on Holiday do you have any suggestions for:
