I've configure all the camera to add onto zoneminder. Unfortunately, there's nothing display (even live view) when i selected one of my monitors. I think the configuration already correct. Any idea for this error ?

Thanks
This solved the problem for me. (Even though this was not selected with earlier versions, and the system worked.)go into options and check HASH_LOGINs... I need to review/cleanup all this AUTh stuff. It's a mess.
