Correct me if I am wrong, but in the past upon registration as users submitted information appeared in the sandbox as well.
To be precise I updated my registration code and since then upon user registration using a custom registration form the input data only appear in the live part of the database, not the sandbox.
Any ideas why this is so?
When you work in the Wix Editor you are working as Admin in the sandbox mode.
When users use the site and register/login etc, they are working in the live mode.
You can’t edit the datasets of Wix apps as they will most likely be set to site member author only meaning that only the specific site member can change anything themselves.
As for datasets that you have added yourself, you can edit them in the sandbox mode, however you would need to then make sure that you sync it to live when you are finished.
Although to do this, you would have to make sure that the sandbox version holds the same info as your existing live version so you might have to sync your live to your sandbox to do that.
Or you can just edit it in the live version.
