Invalid CSRF token on export

[cvladan]

Error: "Invalid CSRF token. Send the form again. If you did not send this request from Adminer then close this page."
Probably session folder is not writable.

That's Adminer's problem, but just to be aware.

@cvladan noted. Thanks for reporting. I'll have to see if I have time to resume work on this plugin again in the future... but for now, it is what it is.
