Carbonite has never been working for me in the classic era client since the launch of TBC classic and WOTLK classic. Both TBC and WOTLK versions worked fine but the classic era version cant start, the map is not shown, the carbonite quest log is not shown ..... basicly it is as the addon is no there or cannot load completely

Ony WOTLK is supported. But please check this issue => #187 Someone wrote which previous version is working for Classic Era.

If you support only WOTLK version why does it appear in the curseforge client in the wow classic (not WOTLK Classic) section and even have an update on 18.07.2023? I use this to update all my addons to the correct working version for every version of the game and it does but it seems to not find the correct version for classichttps://ibb.co/Qv6sn7K

So this is CurseClient issue (the date), report to them. The last update for Classic Era (1.02) was for 1.13.4 version of Client, which is now 1.14 if im not wrong.

As i wrote before see the issue i linked before => #187 maybe this helps.
