Error after add extension

Robertos

Hello.
I have some error when try add extension in admin panel

Flarum encountered a boot error (FastRoute\BadRouteException) Cannot register two routes matching "/admin-mail" for method "POST" thrown in /home/xnpogaw1/domains/xn--pogawdka-reb.pl/public_html/vendor/nikic/fast-route/src/DataGenerator/RegexBasedAbstract.php on line 55

Robertos Which extension did you add? Looks like it's trying to register a route that already exists (based on the Cannot register two routes matching "/admin-mail" for method "POST" error).

i think this is Mailing extension for Flarum

I fix this in command composer remove flagrow/users-list

Robertos do not install flagrow/users-list, it's incompatible with the latest Flarum releases.
