changing hostname locks up system

Hello everyone, I followed the online directions to change my hostname (both /etc/hostname and /etc/hosts) in vim and after rebooting and logging in, I was unable to right click to get my menu (running Openbox on XFCE with obmenu-generator) Changing it back to the original and rebooting makes everything work again.

Dell Inspirion 3583 12G Ram
i3 processor
Artix XFCE running Openbox

Thank you in advance for your help.
