Hi

It looks like a PHP error. Can you check your HTTP and PHP error logs? There is probably some info about the problem.

there is big problem there is no HTTP and PHP error logs

Can you try to run WordPress in debug mode? Maybe it will output the PHP error(s):

1. Open the wp-config.php and locate this line:

define('WP_DEBUG', false);

2. Replace it with:

define('WP_DEBUG', true);

After your test, don’t forget to restore the original line.

You can also try to modify your PHP INI file:

1. Force PHP to ouput error to the screen, open the PHP INI file and add those lines:

; Display errors:
error_reporting = E_ALL | E_STRICT
display_errors = On

2. Force PHP to log errors to file as well, open the PHP INI file and add those lines:

; Log errors:
log_errors = On
error_log = /path/to/errors.log

Replace /path/to/ with the full path where you want the log to be saved.

the same thing ??

You can try to edit the ninjafirewall/install.php script.
Open it and line 21, right after the copyright, add those 2 lines:

error_reporting(-1);
ini_set('display_errors', '1');

Hopefully, that will display the error.

You can also try to add those 2 lines as well:

ini_set("log_errors", 1);
ini_set("error_log", "/path/to/php-error.log");

Here again, replace “/path/to/php-error.log” with the full path where you want the log to be saved.

hi thanks
i solved the problem , it’s from my side not from ninjafirewall or amazon aws.

i was rename index.php to another name , this prevent ninjafirewall to find index.php

ps : update you’r plugin to show error or warning if can’t find index.php

thanks
