v3.2.0

Favorites tab appears bright gray with no buttons available apart from the info/exit buttons and list selection dropdown, which upon clicking does nothing.

This is still happening for me too. I tried uninstalling and reinstalling it but that did not work.

Same

Also happening for me on Anniversary servers.

Copy paste of a fix I found from reddit:

Had the same issue, here's the fix (not mine, Khundian posted this):

You can fix the favorites / wishlist yourself with a simple edit in one of the files.

Open the "Template_CheckBox.lua" file in the "../World of Warcraft/classic_era/Interface/AddOns/AtlasLootClassic/GUI" folder with a text editor like Notepad++.

Look on line 46 for: "OptionsCheckButtonTemplate"

Change to: "OptionsBaseCheckButtonTemplate"

Reload your addons or restart the game, the favorites / wishlist should be working again.

I can confirm this works.
