mix0nSPb when you send a test email does that work?

Apparently not, because I don’t have my own server for sending email, I didn’t set up sending a test email in flarum. now I tried to click on send and I got the same error: "Oops! Something went wrong. Please reload the page and try again."

mix0nSPb that's the issue, then. Flarum will send the activation email when a new user is registered, if this fails an error will be shown. If the mail doesn't go out the user will be unable to activate their account.

If you can't send mails locally using sendmail, you can use an external SMTP server to relay emails.

Everything you said is correct! I just tried to figure it out and put it in the email section: driver -> log. And the error stopped appearing. plus I also installed an Email verification switch to automatically verify users and everything was great! True, letters in this case with notifications will not come, and the truth will not be ...
Now I will figure out how to properly configure an external SMTP server for sending letters!
flarum is a very cool solution, I hope that it will continue to develop!

mix0nSPb Now I will figure out how to properly configure an external SMTP server for sending letters!

You can also use a third party, some of these have free plans with a certain capacity limit. Look at mailgun, sendgrid or alternatives. They are better at handling your email reputation than you have time for 🙂.

Understood, I will definitely consider these options! Thank you so much for helping me resolve the issue!
