I sort of have the same issue. Ever since updating to 8.953 I can’t load dugi guides. I updated using the Dugi 1.5.0. installer. I have the spinning wheel but next to it is the msg “loading Dugi Guides 3%..” and it just stalls with the wheel just spinning endlessly. I first did /dugi fix and reloadui that gets rid of the message and wheel but then I click on the guide and I get a lua error message
“interfaceAddOnsDugisGuideViewerZLuaUtils.lua:31:attempt to index local ‘pString’ (a nil value)”
I’ve deleted the addon and reinstalled it multiple times using the Dugi installer. I also deleted the DugisGuideViewerZ.lua in the character folder and then did a fresh install of the guide nothing is working.
