I think not, but I’m not very expert with this

I don’t see my error coming anywhere. Should I do something with this file /ninjafirewall.php ‘?

You are migrating a site with NinjaFirewall installed. You would need to follow the steps mentioned in the FAQ here (scroll down to “Can I migrate my site(s) with NinjaFirewall installed?”).

PS: Note that NinjaFirewall does not run on Microsoft Windows, it’s a firewall for Unix-like OS.

thanks nintechnet, I followed the steps you put in the link that you have attached. When I uninstall the plugin what I see is that the ninjafirewall files continue to appear in the folder. The problem is still wrong
Should I delete them manually?

The content of the “/wp-content/nfwlog/” folder will remain even after uninstalling NinjaFirewall because they are logs etc.
You can delete it manually if you don’t want to keep it.

The problem continues.
Can I delete the files (htacces.ninja, .user.ninja) ?? Should these files have been deleted after deleting the plugin?

Search and remove any occurrences of NinjaFirewall in your “.htaccess” and “.user.ini” files. They should have been removed during the uninstallation process but they are still there because you made a copy of your site (and the “.htaccess” and “.user.ini”) before uninstalling the firewall.

Thanks this it works!!
