"this content failed to load."

Hello guys,

I have got a problem with my Internetpage. When i try to start a new topic in the forum i can´t write bright letters while pressing the ‘b’ icon. If i do, there is only a message appearing and reporting that “This content failed to load.”

Could you please help me?

Greetings

Quente
