Hi.
I tried to register an account with Firefox on Linux to no avail. As soon as I tried the same values with Chrome it worked.
It always gives some strange error. Like
“Incorrect username, email or password”
Maybe look into that. Another user also reports such an issue. See a topic on Reddit with name “Account on seafile forum?”. I’m not allowed to post a link here.
Just FYI. Obviously I now have an account.
