while i was playing with my friend we went to the nether. but wen we went there we got stuck in the portal because someone put doors there wich were locked and we couldn't use the chat or escape, can someone fix this?

 

I suggest downloading an app on your android or apple mobile device called Minechat. From there you can join Mineverse then execute the following commands:
1. /skygrid - Allows you to join the Skygrid server from a command.
2. /home - Teleports you back to your home point.

That should solve your problem of being stuck. Hope this helped.
