I've used the developer mode so all languages should be installed. I've tried to install the Forum.

With other betas and the same installation behaviour(using developer mode), it works fine. But with beta 5, it stopped working.

Ah, I figured it out. When I am creating the database with "utf8mb4_bin" it won't work. When I let it to the default value, it works.pasted-from-clipboard.png

But maybe you could resolve the exception thrown while the first exception was handled? (It won't check for the class attribute)

And it just works when I'm using the default collation...
