Steam Web API Key

[Deathtitan77]

Hello everyone,

I am struggling a bit because I can't understand why my API key is not functioning as it's supposed to be. I am trying to setup a MyBB website with a Steam login but it's not accepting my API key. This is the error I receive after setting it up with the API key,"Not Configured The Steam Login plugin hasn't been configured correctly. Please ensure an API key is set in the Configuration settings."

Any help would be appreciated, thanks.
