 * Hello,
 * Can’t activate the Wordfence Web Application Firewall :
 * message error :
    The changes have not yet taken effect. If you are using LiteSpeed
   or IIS as your web server or CGI/FastCGI interface, you may need to wait a few
   minutes for the changes to take effect since the configuration files are sometimes
   cached. You also may need to select a different server configuration in order
   to complete this step, but wait for a few minutes before trying. You can try 
   refreshing this page.
 * looked in the php/user.ini to add manualy the code “auto_prepend_file etc…”
    
   the code is already inside.
 * called my host, tried all the web server’s configuration ; apache, litespeed,
   nginx etc
    same issue
 * what can i do please?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fcant-activate-web-application-firewall%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hi [@nicopointcom](https://wordpress.org/support/users/nicopointcom/),
 * In order to make sure which Firewall setup you should be using:
    - Go to the _Wordfence Tools_ page
    - Click the _Diagnostics_ tab
    - In the _Other Tests_ section (near the bottom of the page), click the link
      that reads _“Click to view your system’s configuration in a new window“_. 
      This will open a _Wordfence System Info_ page
 * Check the **Server API** field. Is it consistent with the parameter which is _“
   Recommended based on our tests“_?
 * The issue could also be caused by the [_.user.ini_ file not being processed correctly](https://docs.wordfence.com/en/Web_Application_Firewall_Setup#If_installation_completes_without_errors_but_the_firewall_still_shows_Basic_WordPress_Protection).
 * Could you also please confirm the _PHP_ version you’re running?

    Unfortunately for a bug security
   reason i had to remplace this plugin by anotherone three weeks ago. Then this
   case can be closed (i understood thats your new update had fixed that).
