WHMCS Support Manager WHMCS John Posted February 11, 2021 WHMCS Support Manager Share Posted February 11, 2021 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 0 Quote Link to comment Share on other sites More sharing options...
