This is the only addon I have enabled. I click Save CVars, then the dialog pops up and I click yes but nothing happens. The dialog doesn't go away. When I click restore it says no CVars have been saved.

found the issue. "C_Console.GetAllCommands is now ConsoleGetAllCommands as of 10.2.0". I guess need to replace all of those, maybe? I tested and it seems to work.

Oh thank you! Blizzard does love changing around the API often after every patch. Constantly changing the code (for no reason sometimes) and breaking addons.

Let me take a quick look but you are probably 100% right. I see you made a pull request. I'll merge it once I ping the server real quick to check on ConsoleGetAllCommands.

Okay so I took a look. It seems on the Classic and WOTLK servers it's still C_Console.GetAllCommands() and on the live servers it's now ConsoleGetAllCommands().

Let me take a look at your pull request :)
