I've also discovered your forum project today and installed it. Unfortunately, the plugin BBCode Toolbar did not activate and now I have error messages in the backend and frontend.
These look like this.
Fatal error: Interface 'Psr\Container\ContainerInterface' not found in /xxxxxxxxxxxxxxxxxx/featherbb.wpzweinull.ch/vendor/container-interop/container-interop/src/Interop/Container/ContainerInterface.php on line 14
Can you help me fix it?
Thanks in advance.
The composer I have updated, of course, but the errors are not gone.
