miowski Example : https://forum.aper.me/u/tdsghjkoc (where tdsghjkoc is not an existing user on my instance) I get a weird page. I've tried with discuss.flarum.org/u/[any inexisting user] so I think it shouldn't behave this way on my forum installation. Thanks in advance
miowski If that may help, I had previously migrated my flarum instance from one server to another following this tutorial.
SychO You have to set debug to false in your configuration file config.php located in your flarum installation directory.
