@adriatic Helllo, I just bumped into the issue that you mentioned. The easiest method i found was using an app. Link to download: Version 3.12.1 released - DB Browser for SQLite . Its open source app and provides very easy way to manage tables. Basically you can delete the collections or attributes from strapi admin panel and then delete corresponding tables or columns from the sqlite database using the provided app. Then you are good to go and make changes as you please. Hope it helps!
