Both addons up to date according to curse, were working fine spent hours making settings for them as I want logged out and switched to another character randomly 100% visually broken and unusable with this LUA error.  All characters, all accounts laptop and desktop now.  Bartender not loading?

I'm sorry, I cannot offer support for use of Bartender4 as part of UI packs. You would have to ask the SpartanUI developer about this.
