Im trying to share my deck on ankiweb, but it says error building deck tree, and I cant actually see any of the deck. How do I fix this?
One of your child decks has used a lowercase “igualdad”, when the parent deck name uses an uppercase. If you rename the child deck(s) to match, it should fix the problem.
wow, I didn’t think it was that simple haha!
Thank you so much 
Glad to hear that sorted it. For what it’s worth, AnkiWeb should be able to handle this automatically in the not too distant future.
