I doubt it will be easy/possible as it relies on Wkkyds library LibWykkydFactory4 which was never updated since years. And many other addons of him which also rely on it are not working and were not updated because of that.
So I assume this is not possible. Maybe Sharlikran got that libray "changed" somewhere but I think he said it was not possible.
So do not expect that addon to be fixed, or at least not in near future. Maybe one is able to strip that library and use other code.
But as I do not even know what exactly that addon does and hw it achieves it I cannot say if this is possible without Wykkyd's old discontinued library,
Edit: Had a look at the error message and it
maybe just wrong usage of LAM2 -> LibAddonMenu2
try to change the following lines of file addon.lua
388 and 389
From:
LAM2:RegisterAddonPanel(_addon.Name.."_LAM", panelData)
LAM2:RegisterOptionControls(_addon.Name.."_LAM", optionsTable)
To:
LibAddonMenu2:RegisterAddonPanel(_addon.Name.."_LAM", panelData)
LibAddonMenu2:RegisterOptionControls(_addon.Name.."_LAM", optionsTable)
And install LibAddonMenu's newest version 33 from here to your live/AddOns folder:
https://www.esoui.com/downloads/info7-LibAddonMenu.html
If after that change any other error messages occur, sorry, cannot help any further. Shouldbe the above mentioned library then.
