Invalid CSRF token. Send the form again. Adminer

Question

I am getting this error on export of my database in adminer. Error: Invalid CSRF token. Send the form again. If you did not send this request from Adminer then close this page. Need Help

Answer 1

The problem for me was that the session cookie had the secure flag, while I was accessing adminer via http only (not https).

---

Our nginx configuration had

fastcgi_param HTTPS on;

which I had to remove.

Answer 2

Try this!

chgrp nginx /var/lib/php/session

The problem may cause by session save path not writable. I have faced the same problem and I fixed it by above command. I use nginx but if you use another web server, just change it. Hope this helps!
