Little help for a technophobe - Form security failed

Hey all,

I’ve installed PWIK via cPanel and set it up. It was working yesterday but I’ve gone to log into it today and I get the follow message:

Error: Form security failed. Please reload the form and check that your cookies are enabled. If you use a proxy server, you must configure Piwik to accept the proxy header that forwards the Host header. Also, check that your Referrer header is sent correctly

Is anyone able to help me? I’m not the most technical of people and learning as I go along…



I had the same error after enabling a reverse proxy to reach piwik from Internet. To solve it I had to add the below config on apache vitual host config for piwik:

RemoteIPHeader X-Forwarded-For
RemoteIPInternalProxy YOUR_PROXY_IP

Hope it helps
