I think this is issue related to presence of old Allision folder in the folder /Users/macpro1/Library/Application Support/Allusion once i deleted this it did show properly after restart

We do not handle parsing configurations well. Note the letter case of the class. It is DARK and not dark. We should settle down on a stable format for the final release to avoid breaking the theme for existing users and actually parse the format. As for the error, this one is simple too. I think in previous iterations the id of root tag was a different than now. Therefore in newer versions it would not find the tag anymore.
