Not sure what error this is

[Sayain1989]

My brother and I can't see eachother well we are in the same spot, I'm sure the problem is with him since I can see the private shops where he can see one or two.

Thank you for your help it was really useful we were stuck for so long and finally just gave up and decided to come here for help.

You are probably on different instances. Check which instance you are on by going to the minimap and locating the "L". Tell your brother to click on that to change it to L1. If you haven't already do that for yourself as well.
