Invalid CSRF Protection Token


Recommended Posts

  • WHMCS Support Manager

Hi @Nova,

An "Invalid CSRF Protection Token" could be caused by a few things:

  • You logged out in another tab,
  • Your login session expired since the page was loaded,
  • Your connection's IP address has changed since the page was loaded,
  • A PHP Session misconfiguration on the server
  • A misconfiguration of your proxy/WAF/CDN is causing the IP provided to PHP to change frequently

If it wasn't triggered by the first three operator actions:

Start by reviewing the Configuration > System Health page for any PHP Session configuration warnings, and address those.

If your website is behind a proxy, make sure it's properly configured to pass the visitors IP address consistently through to PHP scripts. 

If you can temporarily disable the Proxy/WAF/CDN on your website, you can configure the Trusted Proxy Settings at the script level, telling WHMCS to expect your proxy. This is discussed in depth here: https://docs.whmcs.com/Trusted_Proxy_Settings
