    Hello,

    after moving my website from server A to B, I wanted to install the Ninja Firewall again. It gets installed but I get this error upon activating it:

    Plugin could not be activated because it triggered a fatal error.

    I checked the PHP log files and I see these errors:

    [28-Sep-2024 11:09:00 UTC] PHP Fatal error: Uncaught Error: Undefined constant "NFW_RULES" in /var/www/website/public_html/wp-content/plugins/ninjafirewall/lib/install_default.php:171

    thrown in /var/www/website/public_html/wp-content/plugins/ninjafirewall/lib/install_default.php on line 171

    What is the problem?

    I can’t reproduce the problem.
    Did you try to uninstall it and then to reinstall it ?
    Make sure to remove any line in your PHI INI (.user.ini) file when you reinstall it, just in case.

    I uninstalled it before the migration to ensure no 500 error code.

    I re-installed it after the migration but I can’t activate it. There is no .user.ini file, it is deleted. I can’t activate the plugin, I get the same error.

    Can you run the troubleshooter script: https://nintechnet.com/share/wp-check.txt

    1. Rename it to “wp-check.php”.
    2. Upload it into your WordPress root folder.
    3. Go to https://YOUR WEBSITE/wp-check.php
    4. Delete it afterwards.

    Hi!

    I got exactly the same problem today, move my website and being unable to activate NinjaFirewall. I deleted the whole folder from the plugins folder and installed NinjaFirewall again afterwards, but not success.

    Can you run this script: https://nintechnet.com/share/ninja-connect.txt
    1. Rename it to “ninja-connect.php”.
    2. Upload it into your website root folder.
    3. Go to https://YOUR WEBSITE/ninja-connect.php
    4. Delete it afterwards.

    That will check if your site can connect to download the rules during the installation process.

    Didn’t change a thing after my last message, but just now I managed to activate the plug-in.

    After it I did try the ninja-connect.php file and got this back:

    Attempting to connect to:
    	* updates.nintechnet.com/index.php (HTTPS): OK
    	* wordpress.nintechnet.com/index.php (HTTPS): OK
    	* pro.nintechnet.com/index.php (HTTPS): OK
    	* api.nintechnet.com/test (HTTPS): OK
    	* plugins.svn.wordpress.org/ninjafirewall/updates/version3.txt (HTTPS): OK


    NinjaFirewall (WP/WP+/Pro/Pro+ editions) connection test script v1.3

    Don’t know what changed since last time, but the problem is fixed for me now.

    I encountered the same issue. After deleting /wp-content/nfwlog, I was able to activate it properly.

    I got the very same problem. Would be great if there would be a fix sometime? Have to move websites from one server to another server fromt time to time.

    This problem seems to be new, because otherwise a migration usually went smoothly (deactivate full-WAFF mode, deactivate Ninja Firewall and uninstall. After the migration, reinstalling the Ninja Firewall always went smoothly)

    Edit: After deleting /wp-content/nfwlog, I was able to activate it properly. Thanks SHAO!!!

    I’m currently looking at it.
    The issue seems very new but the code where the error occurred hasn’t been changed for years.

    I found the problem. I will be fixed in the next release.
