Explore Room configuration under Components - BlastChat Client - Configuration-Server (Joomla admin backend) or "Admin" menu directly inside frontend chat (if you set your username as SuperAdmin yet), there you can find Privileges.

From your Joomla administration, in the same area you have "Logs" there.

I need to enter CHAT-ROOM, anyone see the logs made: "Previous 1 hour | 2 hours | 6 hours | 12 hours | 24 hours"...
How I can remove that option?

Yes I would like to continue keeping the panel from my Joomla Administration.
-------------------------------------

Necesito que al entrar en el CHAT-ROOM, nadie vea los Logs de: "Previous 1 hour | 2 hours | 6 hours | 12 hours | 24 hours!! tal y como me aparece ahora mismo.
¿Cómo puedo quitar esa opción?

Sí me gustaría que se siguiesen guardando en el Panel de Administracion de mi Joomla.
