lostbox66 Hi, there is actually a very simple extension to achieve it. "Email verification switch", https://extiverse.com/extension/isaced/flarum-ext-email-verification-switch, it disabled the email verification. Also, if the error still occurs, you can send a link, I'm also a hidden service owner. By the way, some tor websites ask the users to use tor email, and that is a way. However, if you're using admin account, and this error still occurs, it's not due to the email verification attribute. If this is not an all-time problem, a possible reason is that the tor connection is slow and unstable, your bridge may even change when you're using a website, thus, the connection might already been closed by the server, a possible solution is to change the php setting of these items: max_execution_time, max_input_time, just increase these two values, and make your server to response in a long period of time. If the error is an all-time error, we may need you to show the log to get to know what's the problem. Also, you can try to run the website in the normal internet, or, if you're in the same intranet with the server, run locally and try to see if the error still occurs.
p.s. Just to mention, with no offense, tor is not designed for illegal, but private.
