Error Plugin with Theming CSS

[Niels89]

what is the healt-check saying`? You find it in support : server health check

everything ok?

One way to find the reason:
de-activate all plugins and check if everything is ok without plugins
then install one plugin after the other

Thanks for the answer Connie. I checked the health status and everything there is green, so it means it is ok.

I have tried to disable all the plugins and then I got one error left. I forgot a " ; " in the php code. Then I reactivated all the plugins again, one by one, and my screen isn't white anymore BUT i still got an error in one of the plugings.
