I have updated to version 6.0.6 and am having the below error. I am also having the same problems with frames as everyone else.

14x SpartanUI\core\Handlers\Modules.lua:51: Usage: GetModule(name, silent): 'name' - Cannot find module 'Component_chatbox'.

Just did a little testing and this error goes away if I disable the Prat addon.

If you disable the SUI Chatbox module manually the error will go away. SUI is trying to auto-disable its chat mod when it sees prat and I did not capitalize a letter. will be fixed in 607

/script SUI:DisableModule('Chatbox')
