Have you also just double checked your dataset permissions to make sure that it is still set to write only?
Plus, if it is just for user inputs to be submitted, did you simply use Form Submission?
Also, make sure that the dataset element connection on your page is still connected to the appropriate dataset along with the user input field connections for it too, as well as the submit button itself.
If you have already checked all of the above, then please post your Editor URL so that Sapir can take a look at it.
Only Wix employees have the right permissions to open Editor links, so it is secure to post here.
Otherwise, please add a website link instead.
