I installed a new Server with Zammad 3.3. Last week everything working fine. Today i try to login and got “CSFR Token verification failed” error i can’t login anymore. I tried different Browser, Edge, Firefox.
I rebuild the server with an backup 5 days ago and got the same.
CSRF errors to 98% of the issues come from your webserver.
You do know that the current vhost file does not hold that new directive for the reason this being a sub optimal fix which for this reason is not within the official code base?
Just check your vhost configuration and ensure the said directive is there and put it into your configuration if it’s not. No reason to bark.
