Just to let you know, you are not being ignored.
Have you tried to run Carbonite on it's own with no other addons?
Grid, DBM, recount and Lightheaded you can keep running as I run them with no problems (among the other 80 or so addons I run with)
My finger keeps coming back and pointing at ElvUI though.. There have been quite a few changes to Carb recently and I'm not sure they are gonna change their addon until Rythal has finalised the changes to Carb/Carb2.
I'm sure I have seen the GOpts error before in this forum somewhere.. I'll have a look around, see if I can't find something..
